Photoreductive cyclization of N,N-dialkyl-β-oxoamides: synthesis of piperidines and δ-lactams
摘要:
The photoreductive cyclization of N,N-unsaturated dialkyl-beta-oxoamides produced delta-lactams in good yields. On the contrary the photoreductive cyclization of N,N-unsaturated dialkyl-beta-aminoketones produced substituted piperidines in poor yields.
