The Lewis acid promoted reaction of silyl enol ether to chiral imines and 1,3-oxazolidines derived from (R)-phenylglycinol afforded with good diastereoselectivity the (R,R)-β-amino ester derivatives from the imines, and the (R,S)-β-amino ester derivatives from the 1,3-oxazolidines.
路易斯酸促进的硅基烯醇醚反应生成手性亚胺和来源于(R)-苯基甘氨醇的1,3-噁唑烷,良好的历戒异构选择性地得到来自亚胺的(R,R)-β-氨基酯衍生物和来自1,3-噁唑烷的(R,S)-β-氨基酯衍生物。
