For the total synthesis of novel cyclodepsipeptide homophymine A, (2R,3R,4R)-2-amino-3-hydroxy-4,5-dimethylhexanoic acid was successfully synthesized by Evans' asymmetric alkylation and the anti-selective asymmetric hydrogenation of a chiral α-amino-β-keto ester as the key steps.
为了完全合成新型环二肽高草胺A,成功地通过Evans的不对称烷基化和手性化合物的抗选择性不对称氢化成功合成了(2R,3R,4R)-2-氨基-3-羟基-4,5-二甲基己酸α-氨基-β-酮酸酯为关键步骤。
