Using the Passerini and Ugi reactions as representative tests, the utility of several alpha-substituted ketones R-CO-CH(2)-X (X = sulfonyloxy, acyloxy, azido, halo, hydroxy, and sulfonyl) in isonitrile-based multicomponent reactions was explored. In a relative rate study (R = PhCH(2)CH(2)), each of the alpha-substituted ketones underwent Passerinicondensation more rapidly than the parent ketone. Short
