beta-Methoxytyrosine (beta-OMeTyr) is a stereoundefined component of papuamides A and B, novel cyclodepsipeptides, with anti-HIV and cytotoxic activities. For structural determination and total synthesis of papuamides, all stereoisomers of beta-OMeTyr were stereoselectively prepared from (S)- and (R)-serine, respectively.
β-甲氧基酪氨酸(β-OMeTyr)是木瓜酰胺A和B(新型环二肽)的立体未定义成分,具有抗HIV和细胞毒性作用。为了结构测定和木瓜酰胺的全合成,分别从(S)-和(R)-丝氨酸立体选择性地制备β-OMeTyr的所有立体异构体。
