Prenyl carbamates: Preparation and deprotection

Prenyloxycarbonylimidazole (PreocIm) and prenyl p-nitrophenyl carbonate (PreocOC6H4p-NO2), two substitutes for the unstable prenyl chloroformate, allowed an efficient introduction of the prenyloxycarbonyl group to a variety of primary and secondary amines. Deprotection of prenyl carbamates was readily achieved by, first their conversion to 2-iodo-3-methoxy-3-methylbutyl carbamates with iodine in methanol followed by reductive beta-elimination with zinc powder. These reaction conditions are compatible with the presence of a number of functional groups such as Boc and Cbz carbamates, sulfides, double bonds, indoles and aromatic 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 1745-07-9 is helpful to your research. Synthetic Route of 1745-07-9

Oxidation of Trialkylamines by BrCCl3: Scope, Applications and Mechanistic Aspects

The catalyst-free photochemical reaction of trialkylamines and BrCCl3 induced by visible light was investigated. The outcome of the reaction was found to depend strongly on the nature of the amine substrates. N-Methyl-1,2,3,4-tetrahydroisoquinolines give 3,4-dihydroisoquinolinium salts, whereas aliphatic trialkylamines produce hydrohalide salts and streptocyanines as the major products. The addition of KCN inhibits streptocyanine formation, and results in the clean formation of alpha-aminonitriles instead. The light-absorbing species and the underlying reaction mechanism were studied by DFT calculations and experimental observations.

Rigid: Versus flexible anilines or anilides confirm the bicyclic ring as the hydrophobic portion for optimal sigma2 receptor binding and provide novel tools for the development of future sigma2 receptor PET radiotracers

Despite their uncertain identification, sigma2 receptors are promising targets for the development of diagnostics and therapeutics for tumor diseases. Among the sigma2 ligands developed, the class of the flexible benzamides furnished an optimal pharmacophore for sigma2 receptor high affinity ligands. A recent investigation suggested that flexible benzamides bind sigma2 receptors in a bicyclic-like conformation due to an intramolecular H-bond, with 3,4-dihydroisoquinolinone derivatives reaching excellent sigma2 affinity and selectivity. Herein, the bicyclic-preferred conformation for sigma2 binding was confirmed through the development of 3,4-dihydroquinolin-(1H)2-one isomeric derivatives, 1,2,3,4-tetrahydroquinolines and the corresponding flexible anilides and anilines, all linked to the 6,7-dimethoxytetrahydroisoquinoline as a basic moiety. 3,4-Dihydroisoquinolin-(1H)2-one (10a) and 1,2,3,4-tetrahydroisoquinoline (11b) emerged for high sigma2 affinity combined to an excellent sigma2versus sigma1 selectivity. In particular, compound 11b with its low nanomolar sigma2 affinity and impressive 2807-fold sigma2versus sigma1 selectivity largely exceeded the biological profile of the best 3,4-dihydroisoquinolin-(2H)1-one reference compounds (1). Because of the absence of a cytotoxic effect, the modest interaction with the P-gp, an appropriate lipophilicity and the presence of easily radiolabeling functions, 11b deserves further investigation for the imaging of sigma2 receptors via PET in tumors.

Basicity pK(HB) scale of hydrogen bounding of aliphatic tertiary amines

The hydrogen bond acceptor strength of 40 tertiary amines has been measured by Fourier transform – infrared (FTIR) spectrometry from their 1:1 complexation constant towards 4-fluorophenol in CCl4 at 25C (the pKHB scale). Also measured was the frequency shift, Deltanu(OH), of the nu(OH) band of methanol hydrogen-bonded to these amines. The comparison of the thermodynamic hydrogen bond basicity scale, pKHB, with the spectroscopic one, Deltanu(OH), and with the Bronsted pKa scale, points to the great sensitivity of pKHB to steric effects. The pKHB scale of tertiary amines extends from 2.71 for quinuclidine to -0.34 for N,N-diisopropyl-3-pentylamine. The main factors governing this important variation (17 kJ¡¤mol-1 on the Gibbs energy scale) are the electron-withdrawing inductive effect and various kinds of steric effects (e.g., opening of the CNC angles and hindrance to OH fixation on the nitrogen lone pair). Infrared (IR) spectra show the attachment of 4-fluorophenol to the nitrile nitrogen of Me2NCH2C?N and Me2NCH2CH2C?N, to the oxygen of N-methylmorpholine, and to the pi electrons of (HC?CCH2)3N and (PhCH2)3N, in addition to the attachment to the amino nitrogen. In (PhCH2)3N, the electron-withdrawing effect of the three benzyl substituents and, mainly, the very important congestion of the nitrogen lone pair reduce the nitrogen hydrogen-bond basicity almost to nothing, so that tribenzylamine, a nitrogen Bronsted base, turns to a pi base in hydrogen bonding. From this example, the large differences between the pKHB and pKa scales of organic bases are emphasized.

Iodine release and recovery, influence of polyiodide anions on electrical conductivity and nonlinear optical activity in an interdigitated and interpenetrated bipillared-bilayer metal-organic framework

{[Cu6(pybz)8(OH)2]¡¤I 5-¡¤I7-}n (1), obtained hydrothermally by using iodine molecules as a versatile precursor template, consists of a cationic framework with two types of zigzag channels, which segregate I5- and I7- anions. The framework exhibits the first observed bipillared-bilayer structure featuring both interdigitation and interpenetration. 1 displays high framework stability in both acidic (HCl) and alkaline (NaOH) solutions. 1 slowly releases iodine in dry methanol to give [Cu6(pybz)8(OH)2](I -)2¡¤3.5CH3OH (1′) and partially recovers iodine from cyclohexane to form [Cu6(pybz)8(OH) 2](I-)2¡¤xI2 (1?). Differences of up to 100 times in electrical conductivity and of 4 times in nonlinear optical activity (NLO) have been measured between 1 and 1′. This compound is one of few displaying multifunctionality, electrical conductivity, NLO, and crystal-crystal stability upon release and recovery of iodine. It is also unique in the iodine release from polyiodide anions in a metal-organic framework.

Synthesis of Fused Heterocycles: 1,2,3,4-Tetrahydroisoquinolines and Ring Homologues via Sulphonamidomethylation

The title heterocycles (3) have been obtained by a two-step synthesis; namely an initial intramolecular sulphonamidomethylation of N-aralkylsulphonamides (1) in acid media followed by desulphonylation of compounds (2) under moderate conditions, either by reduction or acid hydrolysis.Generally both steps gave good or high yields of compounds (3) variously substituted in the aromatic ring and with a six-, seven-, or eight-membered heterocyclic ring.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.name: 7-Chloro-1,2,3,4-tetrahydroisoquinoline, you can also check out more blogs about82771-60-6

A synthesis of mono- and dimethoxy-1,2,3,4-tetrahydroisoquinolines via Pummerer reaction: Effects of methoxyl groups on intramolecular cyclization

A synthesis of 1,2,3,4-tetrahydroisoquinolines (TIQs) (23) with one and two methoxyl groups at various positions of the benzene ring was achieved via the intramolecular cyclization of N-(aryl)methyl-2- (phenylsulfinyl)ethylamines (9) using the Pummerer reaction as a key step. The reaction was carried out by using trifluoroacetic anhydride (TFAA) (method A) or TFAA-BF3 ¡¤ Et2O (method B). The cyclization to 4-SPhTIQs (11) proceeded effectively when the reaction center at the benzene ring was electronically activated by a methoxyl group. In the reaction of the sulfoxide (9e) having two OMe groups at ortho- and para-positions a different cyclization reaction leading to a benzothiazepine (12) was observed, indicating that the high nucleophilicity of the benzene ring caused the unexpected reaction prior to the cyclization to 4-SPhTIQ (11e). The route starting from methoxylated benzaldehydes (5) was proved to provide an efficient and convenient method of TIQ synthesis which should be complementary to the well known Pictet-Spengler method.

Conformationally-flexible benzamide analogues as dopamine D3 and sigma2 receptor ligands

A series of conformationally-flexible analogues was prepared and their affinities for D2-like dopamine (D2, D3 and D 4) were determined using in vitro radioligand binding assays. The results of this structure-activity relationship study identified one compound, 15, that bound with high affinity (Ki value=2 nM) and moderate selectivity (30-fold) for D3 compared to D2 receptors. In addition, this series of compounds were also tested for affinity at sigma 1 and sigma2 receptors. We evaluated the affinity of these dopaminergic compounds at sigma receptors because (a) several antipsychotic drugs, which are high affinity antagonists at dopamine D 2-like receptors, also bind to sigma receptors and (b) sigma receptors are expressed ubiquitously and at high levels (picomoles per mg proteins). It was observed that a number of analogues displayed high affinity and excellent selectivity for sigma2 versus sigma1 receptors. Consequently, these novel compounds may be useful for characterizing the functional role of sigma2 receptors and for imaging the sigma2 receptor status of tumors in vivo with PET.
