Electrochemical Oxidative Amination of Sodium Sulfinates: Synthesis of Sulfonamides Mediated by NH4I as a Redox Catalyst

An efficient protocol for the synthesis of sulfonamides via the electrochemical oxidative amination of sodium sulfinates has been developed. The chemistry proceeds in a simple undivided cell employing a substoichiometric amount of NH4I that serves both as a redox catalyst and a supporting electrolyte; in this manner additional conducting salt is not required. A wide range of substrates, including aliphatic or aromatic secondary and primary amines, as well as aqueous ammonia, proved to be compatible with the protocol. Scale-up was possible, thereby demonstrating the practicality of the approach. The electrolytic process avoids the utilization of external oxidants or corrosive molecular iodine and therefore represents an environmentally benign means by which to achieve the transformation.

Visible light catalyzed Mannich reaction between: Tert -amines and silyl diazoenolates

The present work documents the alpha-C-H functionalization of tertiary amines via the visible light catalyzed Mannich reaction with silyl diazoenolates. The reaction takes place at room temperature with an organic dye, Rose Bengal, as a photocatalyst and oxygen as the oxidant. The resulting multifunctional products bearing an alpha-diazo-beta-keto group undergo Rh-carbenoid mediated cyclization, affording stable ammonium ylides in high yields.

Examination of the role of the acidic hydrogen in imparting selectivity of 7-(aminosulfonyl)-1,2,3,4-tetrahydroisoquinoline (SK and F 29661) toward inhibition of phenylethanolamine N-methyltransferase vs the alpha2-adrenoceptor

7-(Aminosulfonyl)-1,2,3,4-tetrahydroisoquinoline (SK and F 29661, 1) is a potent inhibitor of the enzyme phenylethanolamine N-methyltransferase (PNMT, EC 2.1.1.28). In contrast to other inhibitors of PNMT, it is also highly selective toward PNMT in comparison with its affinity toward the alpha2- adrenoceptor (PNMT K(i) = 0.55 muM, alpha2 K(i) = 100 muM, selectivity [alpha2 K(i)/PNMT K(i)] = 180). A diverse set of compounds was synthesized and evaluated to probe the role of the acidic hydrogen of the aminosulfonyl group of 1 in imparting this selectivity. Compounds were designed to investigate the effect on selectivity of the acidity of the NH group [the 7-N-methyl (compound 5) and 7-N-(p-chlorophenyl) (compound 4) derivatives of 1], the relative spatial position of the acidic hydrogen [7-(N- (methylsulfonyl)amino)-1,2,3,4-tetrahydroisoquinoline (6) and 7-((N- (methylsulfonyl)amino)methyl)-1,2,3,4-tetrahydroisoquinoline (8)], or the effect of the substitution of an acidic phenolic group for the aminosulfonyl moiety [1-(aminomethyl)-6-hydroxynaphthalene (28) and 8-hydroxy-1,2,3,4- tetrahydrobenz[h]isoquinoline (9)]. All of the compounds studied displayed lower affinity for PNMT than 1, and nine of the eleven compounds studied showed increased, rather than the desired decreased, affinity for the alpha2- adrenoceptor. Specifically, compound 4, in which the aminosulfonyl NH group is more acidic than that in 1, showed greatly reduced selectivity on account of increased alpha2-adrenoceptor affinity as compared to 1 (PNMT K(i) =- 2.6 muM, alpha2 K(i) = 6.3 muM, selectivity = 2.4). Compound 8, in which the acidic NH group is in the same region of space as that in 1, although the aminosulfonyl group is reversed with respect to the aromatic ring, showed poor PNMT affinity and modest alpha2-adrenoceptor affinity (PNMT K(i) = 330 muM, alpha2 K(i) = 18 muM, selectivity = 0.055). Compound 9, in which a phenolic group is in the same region of space as the acidic NH of 1, exhibited the best alpha2-adrenoceptor affinity of any of the compounds studied (PNMT K(i) = 0.98 muM, alpha2 K(i) = 0.078 muM, selectivity = 0.080). Results from this study suggest that the selectivity of 1 is not solely due to the presence of an acidic hydrogen on the 7-aminosulfonyl group of 1 but is likely also dependent on some other property (e.g. electron-withdrawing character) of the aminosulfonyl group.

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 42923-79-5 is helpful to your research. Reference of 42923-79-5
