New and efficient synthetic routes to 2-alkylisoserines, their dipeptides and 2′-alkyl-taxoids were synthesized from enantiopure 3-alkyl-β-lactams 3 which were obtained through extremely distereoselective alkylation of β-lactams 2.
从对映体纯的3-烷基-β-内酰胺3合成了2-烷基异丝氨酸,其二肽和2'-烷基-类紫杉醇的新型有效合成路线,所述对映纯的3-烷基-β-内酰胺3是通过对β-内酰胺2的极度立体选择性烷基化而获得的。
