from the kinetic resolution of (R, S)- α- furfuryl amide using the modified Sharpless asymmetric epoxidation, have been transformed into four δ-hydroxy α-amino lactones (1S, 3S)-1, (1R, 3R)-1, (1S, 3R)-1, (1R, 3S)-1, using Sharpless asymmetric dihydroxylation as the key step. The much more efficient method of the addition of chiral aldimine 10 with allylic Grignard reagent for preparation of (S, S)-1
(S)-和(R)-α-糠基酰胺,是通过使用修饰的Sharpless不对称环氧化反应从(R,S)-α-糠基酰胺的动力学拆分获得的,已转化为四个δ-羟基α-氨基内酯( 1S,3S)-1,(1R,3R)-1,(1S,3R)-1,(1R,3S)-1,以Sharpless不对称二羟基化为关键步骤。还实现了将手性醛亚胺10与烯丙基格利雅试剂添加以制备(S,S)-1的更有效的方法。
