An intramolecular Michael reaction strategy for the synthesis of 2,6-disubstituted-3-piperidinols
摘要:
A new synthetic strategy for 2,6-disubstituted-3-hydroxypiperidines via intramolecular Michael reaction of an alpha-amino-beta-hydroxy-delta-acrylate is described. The latter was derived from L-alanine in a few steps via the key intermediacy of an enantiopure gamma-amino-beta-keto sulfone. (C) 2002 Published by Elsevier Science Ltd.
