Phosphoryl chloride-mediated solvent-free synthesis of N-aryl-substituted azacycles from arylamines and cyclic ethers

A solvent- and metal-free protocol for preparation of N-aryl substituted azacycles from arylamines and cyclic ethers is described. In this method, the combination of POCl3 and DBU is crucial for conversion of arylamines and cyclic ethers to five- and six-membered azacycles. Without solvent, a variety of N-aryl-substituted, five-membered azacycles (pyrrolidines, 2-methylpyrrolidines, and piperidine) and six-membered azacycles (isoindolines and tetrahydroisoquinolines) are synthesized in high yields. This green method provides a sustainable and efficient approach for the preparation of azacycles from various cyclic ethers.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 3340-78-1 is helpful to your research. Electric Literature of 3340-78-1

Direct analysis of complex mixtures by mass spectrometry

Mixture analysis can provide information on individual components if the sample is first subjected to chromatographic separation. Two critical capabilities, soft ionization and the ability to mass-select and then dissociate ions of a particular m/z, coalesced in 1975, allowing direct analysis of complex mixtures by mass spectrometry. Chemical ionization was used as the soft ionization method and mass-analysis used the ion kinetic energy spectrometer (MIKES). Soft molecular ionization produces a set of ions that are structural surrogates of the neutral molecules; they can be mass-selected and allowed to spontaneously dissociate (i.e. as metastable ions) or fragmented upon energy transfer e.g. in the course of collision-induced dissociation (CID). The second stage of mass analysis provides information about the atomic connectivity in the precursor ion and by implication in the original molecule. This review focuses on the development of complex mixture analysis by mass spectrometry and allied topics. Discussion of the activation techniques associated with (collision-induced dissociation, surface-induced dissociation and metastable ion dissociation) emphasizes the importance of energy transfer phenomena and the internal energies distributions of ions to explain the observed mass spectra. The translational to internal energy transfer in collisions is readily accessed in the MIKES where the second stage mass analyzer is a kinetic energy/charge analyzer. Collisions in the keV range can also be used to change ion the charge state via the processes of charge exchange, electron stripping, or charge inversion. New ionization sources for analysis of non-volatile compounds that were introduced during the time period (1975-1990) of this review included secondary ion mass spectrometry, plasma desorption and field ionization and they are briefly discussed. Several types of scans were developed to rapidly access information of the individual components, including chemically specific scans (e.g. neutral loss scans of mass 30 for nitro compounds).

Compound 48/80. Structure activity relations and poly THIQ, a new, more potent analog

Derivatives of p methoxyphenethylmethylamine were synthesized from which formaldehyde copolymers analogous to compound 48/80 were prepared. Measurement of the hypotensive activity of these analogs revealed that potency was not enhanced by changing the group in the para position, by varying the length of the alkyl group, or by altering the degree of methylation of the amine. However, when the ethylamine side chain was cyclized to form 7 methoxytetrahydroisoquinoline, the copolymer prepared from this derivative (poly THIQ) was seven times more potent than compound 48/80. The hypotensive action of poly THIQ was found to result from the liberation of histamine, as with compound 48/80.

Synthesis of Polycyclic Imidazolidinones via Amine Redox-Annulation

alpha-Ketoamides undergo redox-annulations with cyclic secondary amines, such as 1,2,3,4-tetrahydroisoquinoline, pyrrolidine, piperidine, and morpholine. Catalytic amounts of benzoic acid significantly accelerate these transformations. This approach provides polycyclic imidazolidinone derivatives in typically good yields.

Evaluation of antidepressant activity of 1-(7-methoxy-2-methyl-1,2,3,4-tetrahydro-isoquinolin-4-YL)-cyclohexanol, a beta-substituted phenylethylamine in mice

The beta-phenylethylamines are known to act as ligands for the trace amine receptors, a novel family of G-protein-coupled receptors. The trace amines are stored and released along with various neurotransmitter agents such as norepinephrine, serotonin, and dopamine and thus work as neuromodulator or neurotransmitter agents. Trace amines are known to play an important role in the pathophysiology of major depression. In our earlier study, we have demonstrated the synthesis of various beta-substituted phenylethylamine molecules hypothesized to be effective in various central nervous system disorders. The present study is an attempt to evaluate one of such molecules, 1-(7-methoxy-2-methyl-1,2,3,4-tetrahydro-isoquinolin-4-yl)-cyclohexanol, in animal models of depression. Various behavioral paradigms of despair such as forced swim and tail-suspension tests were used to assess the antidepressant-like activity. Further, an alteration in the levels of various neurotransmitters (norepinephrine, serotonin, and dopamine) in the mouse brain following 1-(7-methoxy-2-methyl-1,2,3,4-tetrahydro-isoquinolin-4-yl)-cyclohexanol administration was evaluated. The molecule (4-16. mg/kg., i.p.) dose-dependently inhibited the immobility period in mouse forced swim test, the effect comparable to venlafaxine. The ED50 values of 1-(7-methoxy-2-methyl-1,2,3,4-tetrahydro-isoquinolin-4-yl)-cyclohexanol and venlafaxine in mouse forced swim test were found to be 5.27 [4.38-6.35] mg/kg., i.p and 4.66 [3.48-6.25] mg/kg., i.p., respectively. Further, 1-(7-methoxy-2-methyl-1,2,3,4-tetrahydro-isoquinolin-4-yl)-cyclohexanol at 4-16. mg/kg., i.p. reversed the immobility period in mouse tail-suspension test. Additionally, the molecule at 8. mg/kg., i.p. reversed reserpine-induced behavioral despair in mouse forced swim test. When administered simultaneously, it (4 and 8. mg/kg., i.p) enhanced the antidepressant activity of sub-effective doses of imipramine (2. mg/kg., i.p.) or fluoxetine (2. mg/kg., i.p.) in the mouse forced swim test. Neurochemical analysis revealed that the molecule at 8. mg/kg., i.p. increased the levels of norepinephrine (21% increase) without affecting serotonin in the mouse brain. However, at higher dose (16. mg/kg., i.p.), it increased the levels of norepinephrine (13% increase), serotonin (37% increase), and dopamine (42% increase). The molecule enhanced the locomotor activity in mice only at higher doses. The molecule, unlike venlafaxine, which potentiated barbiturate-induced hypnosis, was devoid of any sedative activity. In conclusion, 1-(7-methoxy-2-methyl-1,2,3,4-tetrahydro-isoquinolin-4-yl)-cyclohexanol, possess antidepressant-like activity in animal models of depression by modulating the neurotransmitter levels in the brain. Such an activity might be due to the modulating action of this novel molecule on trace amine receptors. Such a molecule may be the future drugs of choice for the treatment of major depression.

Synthesis, biochemical evaluation, and classical and three-dimensional quantitative structure-activity relationship studies of 7-substituted- 1,2,3,4-tetrahydroisoquinolines and their relative affinities toward phenylethanolamine N-methyltransferase and the alpha2-adrenoceptor

7-Substituted-1,2,3,4-tetrahydroisoquinolines (7-substituted-THIQs) are potent inhibitors of phenylethanolamine N-methyltransferase (PNMT, EC 2.1.1.28), the enzyme involved in the biosynthesis of epinephrine. Unfortunately, most of these compounds also exhibit strong affinity for the alpha2-adrenoceptor. To design a selective (PNMT vs alpha2-adrenoceptor affinity) inhibitor of PNMT, the steric and electrostatic factors responsible for PNMT inhibitory activity and alpha2-adrenoceptor affinity were investigated by evaluating a number of 7-substituted-THIQs. A classical quantitative structure-activity relationship (QSAR) study resulted in a three-parameter equation for PNMT (PNMT pK(i) = 0.599pi – 0.0725MR + 1.55sigma(m) + 5.80; n = 27, r = 0.885, s = 0.573) and a three-parameter equation for the alpha2- adrenoceptor (alpha2 pK(i) = 0.599pi – 0.0542MR – 0.951sigma(m) + 6.45; n = 27, r = 0.917, s = 0.397). These equations indicated that steric effects and lipophilicity play a similar role at either active site but that electronic effects play opposite roles at either active site. Two binding orientations for the THIQs were postulated such that lipophilic and hydrophilic 7- substituents would not occupy the same region of space at either binding site. Using these two binding orientations, based on the lipophilicity of the 7-substituent, comparative molecular field analysis (CoMFA) models were developed that showed that the steric and electrostatic interactions at both sites were similar to those previously elaborated in the QSAR analyses. Both the QSAR and the CoMFA analyses showed that the steric interactions are similar at the PNMT active site and at the alpha2-adrenoceptor and that the electrostatic interactions were different at the two sites. This difference in electrostatic interactions might be responsible for the selectivity of THIQs bearing a nonlipophilic electron-withdrawing group at the 7-position. These QSAR and CoMFA results will be useful in the design of potent and selective (PNMT vs alpha2-adrenoceptor affinity) inhibitors of PNMT.

A new ZnIIcoordination polymer based on 4-(Pyridin-4-yl)benzoic and formic acids: In-situ synthesis, crystal structure and luminescence properties

The title compound, poly[(mu2-formato-kappa3O,O?:O)[mu2-4-(pyridin-4-yl)benzoato-kappa3N:O,O?]zinc(II)], [Zn(C12H8NO2)(HCOO)]n, has been synthesized in situ and characterized by thermogravimetric analysis (TGA) and single-crystal and powder X-ray diffraction analyses. The polymer contains two independent structural units in the asymmetric unit. These are constructed from Zn2+ions, 4-(pyridin-4-yl)benzoate (4-pbc) bridges and in-situ-generated formate ligands, forming two similar two-dimensional (2D) layer structures. These similar 2D layers are arranged alternately and are linked with each other by dense C-H¡¤¡¤¡¤O hydrogen bonds to generate a three-dimensional (3D) supramolecular framework. The crystal is pseudomerohedrally twinned about [201]. Compared with free 4-Hpbc, the polymer exhibits a red shift and significantly enhanced solid-state luminescence properties.
