One-Pot Synthesis of Highly Functionalized Stable Ketenimines by Three-Component Reaction of Cyclohexyl Isocyanide, Dialkyl Acetylenedicarboxylates, and Benzoyl Hydrazones
Abstract The adduct produced in the reactionbetween cyclohexyl isocyanide and dialkylacetylenedicarboxylates was trapped by benzoyl hydrazones to afford highlyfunctionalized ketenimines in good yields. The reaction is characterized by mild conditions, high selectivity, and tolerance to various functional groups.
