摘要

Abstract A cascade organocatalysis is reported for the nucleophilic and electrophilic dual activation taking place in the reaction of methyl ketones or active methylene compounds with DMF-DMA (N, N-dimethylformamide dimethyl acetal). L-Proline serves as an efficient organocatalyst in the covalent and noncovalent synchronous mode for the ambiphilic activation of various aryl, heteroaryl, and styryl methyl ketones, cyclic ketones, and 1, 3- ...
