  A Strategy for the Synthesis of Aryl α-Ketoamides Based upon the Acylation of Anions Derived from Cyanomethylamines Followed by Oxidative Cleavage

  摘要：

  [GRAPHICS]Cyanomethylamines, prepared by alkylation of amines with chloroacetonitrile, were deprotonated using NaHDMS in THF, reacted with heteroaryl or substitutedphenyl esters, and then oxidized by adding Clorox(TM) to afford aryl alpha-ketoamides in a single operation In good overall yields.

  The preparation of 2-pyridyl- and 4-pyridylglyoxylic esters and amides in moderate to high yields via palladium-catalyzed double carbonylation of 2-iodo- and 4-iodopyridines is reported. The effect of temperature, CO pressure, solvent, nature and concentration of nucleophile, nature of catalyst precursor, and substituents on iodopyridines has been investigated. The reduction of 4-pyridylglyoxylate esters into the corresponding alpha -hydroxy esters via ruthenium-catalyzed asymmetric hydrogenation or using alpine-borane proceeded in high yields but poor enantioselectivity. The results for the carbonylation and the hydrogenation catalytic processes are discussed in terms of electronic effects induced by the pyridyl ring.
