Zinc Chloride Promoted Formal Oxidative Coupling of Aromatic Aldehydes and Isocyanides to α-Ketoamides
摘要:
Reaction of aromatic aldehydes and isocyanides in the presence of N-methylhydroxyamine, acetic acid, and zinc chloride affords the aryl alpha-ketoamides in moderate to good yields.

combination of an Ugi-4CR and a transition metal-free selective N−S bond cleavage and C−N bond activation, diverse primary amides and α-ketoamides were simultaneously obtained in a highly efficient, rapid, and step-economical manner. The reaction features broad substrate scope, excellent functional-group tolerance, and exclusive selectivity. Primary amides derived from the pharmaceuticals probenecid and febuxostat
