Syntheses of the marine metabolites verongamine, hemibastadin-2, and aerothionin have been accomplished by a methodology involving the conversion of a carboxylic acid to an acyl cyano phosphorane which may be oxidized to an alpha,beta-diketo nitrile. This strongly electrophilic intermediate is rapidly converted by amines to alpha-keto amides.
