    摘要: A process for preparing 3.beta.-amino-4.beta.-substituted-2-azetidinones, which comprises condensing a 3.alpha.-amino-4.beta.-substituted-2-azetidinone with a trihalogenoacetaldehyde or the reactive derivative thereof to give a 3.alpha.-(2,2,2-trihalogenoethylidene)amino-4.beta.-substituted-2-azetidinones, treating the latter with a base to give a 3-(2,2-dihalogenovinyl)imino-4.beta.-substituted-2-azetidinone, reducing the latter with a metal hydride to give a 3.beta.-(2-halogenovinyl)amino-4.beta.-substituted-2-azetidinone, and hydrolyzing the latter to give the objective compound.
