Synthesis of the Bicyclic Secondary Amines via Dimethylaminomethylene Ketones from 3-Pyrrolidone and 4-Piperidone
摘要:
The reaction of N-protected 3-pyrrolidone and 4-piperidone with N,N-dimethylformamide dimethyl acetal gave the dimethylaminomethylene ketones, which reacted with several types of hydrazines, amidines, and guanidine to afford the secondary amines having fused ring system.
