The N-Benzyl imine derived from 2,3-di-O-benzyl-D-glyceraldehyde reacts with Danishefsky's diene to afford the corresponding hetero Diels-Alder adduct with a high diastereoselectivity. This compound can be transformed to enantiomerically pure (2R)-4-oxopipecolic acid. © 1997 Elsevier Science Ltd.
衍生自2,3-二-O-苄基-D-甘油醛的N-苄基亚胺与Danishefsky的二烯反应,以提供具有高非对映选择性的相应杂Diels-Alder加合物。该化合物可以转化为对映体纯的(2 R)-4-氧代哌酸。©1997爱思唯尔科学有限公司。
