摘要：
N-[alpha-(2-Bromo-1-butenyl)-alpha-methyl]oxazolin-2-one (7) and N-[alpha-(2-bromo-1-butenyl)-alpha-pyranyloxyethyl]oxazolin-2-one (14), obtained by starting with ethyl acetoacetate, were treated with tributyltin hydride in the presence of AIBN afforded the cyclization products (8) and (15), respectively, with high diastereoselectivity. Conversion of the 8-methyleneoxazolidinopiperidine (15) to the 6-hydroxyethyl-2-hydroxymethyl-3-hydroxypiperidine derivative (18) was described.
