In cyanation reactions, the cyanide source is often directly added to the reaction mixture, which restricts the choice of conditions. The spatial separation of cyanide release and consumption offers higher flexibility instead. Such a setting was used for the cyanation of iminium ions with a variety of different easy-to-handle HCN sources such as hexacyanoferrate, acetonitrile or alpha-amino acids. The latter substrates were first converted to their corresponding nitriles through oxidative decarboxylation. While glycine directly furnishes HCN in the oxidation step, the aliphatic nitriles derived from alpha-substituted amino acids can be further converted into the corresponding cyanohydrins in an oxidative C-H functionalization. Mn(OAc)2 was found to catalyze the efficient release of HCN from these cyanohydrins or from acetone cyanohydrin under acidic conditions and, in combination with the two previous transformations, permits the use of protein biomass as a non-toxic source of HCN.

Molecular knowledge of pure antagonism and systematic SAR study offered a direction for structural optimization of DIMN to provide nicotinamides as a novel series of AR antagonists. Nicotinamides with extended linear scaffold bearing sterically bulky alkoxy groups on isoquinoline end were synthesized for H12 displacement. AR binding affinity and molecular basis of antiandrogenic effect establish the optimized derivatives, 7au and 7bb, as promising candidates of second generation AR antagonists for advanced prostate cancer.

A novel tetrazole-containing triphenylamine-based MOF {TBA[Cu2(TPA)]}·CH3CN (Cu?TPA; TBA = tetrabutylammonium cation) has been solvothermally synthesized by the reaction of CuCl2·2H2O, tris(4-(2H-tetrazol-5-yl)phenyl)amine (H3TPA) and (TBA)4[W10O32] and structurally characterized by IR spectrum, UV?Vis spectrum, fluorescence analysis, powder X-ray diffraction (PXRD) and single-crystal X-ray diffraction. More interestingly, Cu?TPA exhibits remarkable heterogeneous photocatalytic property and promotes the oxidative C[sbnd]C coupling reaction under mild conditions. The high catalytic efficiency, high stability and good recyclability of the photocatalyst Cu?TPA demonstrate the superiority of the tetrazole-containing triphenylamine-based MOF over homogeneous systems and other noble-metal-catalyzed methods.

We report herein our mechanistic studies of the ortho-quinone-catalyzed aerobic oxidation of primary, secondary, and tertiary amines. Two different catalytic pathways were discovered for the reductive half reactions: for primary amines, the reaction was found to proceed via a transamination pathway, while the reactions with secondary amines and tertiary amines proceeded via hydride transfer. We also found that the amine substrates could significantly promote the regeneration of the ortho-quinone catalyst in the oxidative half reaction, in which a proton transfer occurs between the amine substrates and catechol derivatives (the reduced form of the ortho-quinone catalyst).

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. 1745-07-9

In a search for inhibitors of epinephrine biosynthesis as potential therapeutic agents, a series of 13 ring-chlorinated 1,2,3,4-tetrahydroisoquinolines was prepared. These compounds were tested initially for their ability to inhibit rabbit adrenal phenylethanolamine N-methyltransferase (PNMT) in vitro. Enzyme-inhibitor dissociation constants, determined for the six most potent members of the series, indicated the following order of decreasing potency: 7,8-Cl2>6,7,8-Cl3>7-Cl~8-Cl>5,6,7,8-Cl4>5,7,8-Cl3. These compounds were subsequently examined for PNMT-inhibiting activity in intact rats and mice. 7,8-Dichloro-1,2,3,4-tetrahydroisoquinoline (SK&F 64139) was the most potent member of the series both in vitro and in vivo and is currently undergoing clinical investigation.

Despite recent advances in the field of C(sp2)-C(sp3) cross-couplings and the accompanying increase in publications, it can be hard to determine which method is appropriate for a given reaction when using the highly functionalized intermediates prevalent in medicinal chemistry. Thus a study was done comparing the ability of seven methods to directly install a diverse set of alkyl groups on “drug-like” aryl structures via parallel library synthesis. Each method showed substrates that it excelled at coupling compared with the other methods. When analyzing the reactions run across all of the methods, a reaction success rate of 50% was achieved. Whereas this is promising, there are still gaps in the scope of direct C(sp2)-C(sp3) coupling methods, like tertiary group installation. The results reported herein should be used to inform future syntheses, assess reaction scope, and encourage medicinal chemists to expand their synthetic toolbox.
