Chiral beta-amino esters are synthesized in one-pot from three components, amines, aldehydes, and ethyl bromoacetate, under the rhodium-catalyzed Reformatsky-type reaction condition, where complete diastereoselection is achieved in the nucleophilic addition step of ethyl bromoacetate to the imines prepared in
在铑催化的Reformatsky型反应条件下,由三种组分(胺,醛和溴乙酸乙酯)一锅合成手性β-氨基酯,其中在溴乙酸乙酯与亚胺的亲核加成步骤中实现了完全的非对映选择性。准备在
