Explicit Solvation of Carboxylic Acids for Vibrational Circular Dichroism Studies: Limiting the Computational Efforts without Losing Accuracy

On the basis of a comprehensive analysis of experimental and theoretical IR and vibrational circular dichroism (VCD) spectra, we make suggestions for solvation schemes for carboxylic acids. More specifically, we have studied two chiral carboxylic acids in solvents of different polarity and hydrogen bonding capabilities and verify previously proposed solute-solvent structures for their general applicability. Explicit solvation with acetonitrile-d3 is shown to be most important for carboxylic acid groups directly attached to a stereocenter, while dimethylsulfoxide-d6 should always be considered explicitly in spectra analysis. In order to circumvent the need to consider dimerization with calculations on the full homodimer in nonpolar solvents such as chloroform-d1, we quantitatively evaluate the quality of truncated models. Methanol-d4 is concluded to be the most challenging solvent for VCD studies of carboxylic acids, as the acid strength affects the hydrogen bonding strength to methanol and thus significantly determines the degree and effect of solvation. With the help of matrix-isolation IR spectroscopy, we also characterize the monomeric species of alpha-phenylpropionic acid.

Difunctionalization of the C-N Bond through tert-Butylnitrite-Initiated C-N Cleavage of 1,2,3,4-Tetrahydroisoquinolines and N, N?-Diarylimidazolidines under Transition-Metal-Free Conditions

Difunctionalization of the saturated C-N bond of 1,2,3,4-tetrahydroisoquinolines and N,N?-diarylimidazolidines was achieved using TBN as the metal-free initiator, providing a series N-nitrosoaminoaldehydes in high yields. Mechanistic study shows that the TBN-derived tBuO radical initiated the sp3 C-H bond activation, and the C-N bond cleavage was mediated by an iminium intermediate. This reaction provided a new way to cleave an inert C-N bond under mild and metal-free conditions, realizing the construction of molecular complexity through difunctionalization of the C-N bond.

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.Recommanded Product: 2-Phenyl-1,2,3,4-tetrahydroisoquinoline, you can also check out more blogs about3340-78-1

Selective Hydrogenation of Carboxylic Acids to Alcohols or Alkanes Employing a Heterogeneous Catalyst

The chemoselective hydrogenation of carboxylic acids to either alcohols or alkanes is reported, employing a heterogeneous bimetallic catalyst consisting of rhenium and palladium supported on graphite. alpha-Chiral carboxylic acids were hydrogenated without loss of optical purity. The catalyst displays a reverse order of reactivity upon hydrogenation of different carboxylic functions with esters being less reactive than amides and carboxylic acids. This allows for chemoselective hydrogenation of an acid in the presence of an ester or an amide function.

Partial purification and substrate specificity of flavin-containing monooxygenase from rat brain microsomes

Flavin-containing monooxygenase (FMO) was partially purified from rat brain microsomes through two successive chromatographies on columns of DEAE Sepharose and 2′,5′-ADP Sepharose. The specific activity, benzydamine N- oxidation of partially purified brain FMO, was 122-fold higher than that of microsomes. A single band of 60 kDa was recognized by Western blotting analysis with anti-rat liver FMO. The K(m) value of brain FMO for thiourea was 4-fold lower, but that for cysteamine was 10-fold higher than that of liver FMO. The enzymatic activity for n-octylamine was detected in neither brain nor liver FMO. Kinetic analysis for neurotoxins also revealed that K(m) values of brain FMO for 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP), 1,2,3,4-tetrahydroisoquinoline (TIQ) and N-methyl TIQ (NMTIQ) were lower than those of liver FMO. These results indicate that rat brain FMO catalyzes several substrates of liver FMO involving neurotoxins, but it seems likely that the kinetic properties of brain FMO are somewhat different from those of liver FMO.

New azole antifungals. 2. Synthesis and antifungal activity of heterocyclecarboxamide derivatives of 3-amino-2-aryl-1-azolyl-2-butanol

A series of 92 azole antifungals containing an amido alcohol unit was synthesized. The nature and substitution of the amide portion was systematically modified in search of improved antifungal activity, especially against filamentous fungi. The compounds were tested in vitro against a variety of clinically important pathogens and in vivo (po) in a murine candidosis model. Thiazole and thiophene carboxamides carrying both a substituted phenyl ring and a small alkyl group were best suited for activity against filamentous fungi. In a subset of these compounds, the amide portion was conformationally locked by means of a pyrimidone ring and it was proven that only an orthogonal orientation of the phenyl ring yields bioactive products. A tendency to display long plasma elimination half-lives was observed in both series. Two compounds, 74 and 107, representative of the open and cyclic amides, respectively, were chosen for further studies, based on their excellent activity in in vivo murine models of candidosis and aspergillosis. This work describes the SARs found within this series. The next paper displays the results obtained in a related series of compounds, the quinazolinones.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 61563-33-5, help many people in the next few years.name: 8-Chloro-1,2,3,4-tetrahydroisoquinoline hydrochloride

Lewis Acid-Catalyzed C(sp3)?C(sp3) Bond Forming Cyclization Reactions for the Synthesis of Tetrahydroprotoberberine Derivatives

An efficient Lewis acid-catalyzed C(sp3)?C(sp3) bond forming annulation reaction has been developed. This strategy serves as a new method for the facile synthesis of tetrahydro-5H-isoquinolino[2,1-g][1,6]naphthyridine derivatives. A wide range of 2-methylquinoline-3-carbaldehydes and 1,2,3,4-tetrahydroisoquinolines can be applied for this process to afford structurally diverse tetrahydroprotoberberine derivatives in excellent yields.

Palladium-Catalyzed Directed C(sp3)-H Arylation of Saturated Heterocycles at C-3 Using a Concise Optimization Approach

Saturated heterocycles, such as THFs, pyrrolidines, piperidines and THPs, are essential components of many biologically active compounds. Examples of C-H functionalization on these important ring systems remain scarce, especially at unactivated positions. Here we report the development of conditions for the palladium-catalyzed stereoselective C(sp3)-H arylation at unactivated 3-positions of 5- and 6-membered N- and O-heterocycles with aminoquinoline directing groups. Subtle differences in substrate structures altered their reactivity significantly; and different conditions were required to achieve high yields in each case. Successful conditions were developed using a short empirical optimization approach to cover reaction space with a limited set of variables. Excellent cis-selectivity was achieved in all cases, except for the THP substrate where minor trans-products were formed through a different palladacyclic intermediate. Here, differences in reactivity and selectivity with other directing groups were examined.
