Synthesis of the C6–C18 domain of pamamycin-607 was achieved in ten steps and 7% overall yield from commercially available d-norvaline. The key asymmetric transformations included a Paterson anti aldol addition, an anti selective reduction of the resultant β-hydroxy ketone and a cis selective Bartlett type ring closure.
帕马霉素-607的C6-C18结构域的合成可通过十个步骤完成,而市售d-正缬氨酸的总产率为7%。关键的不对称转化包括Paterson抗羟醛加成,所得β-羟基酮的抗选择性还原和顺式选择性Bartlett型环闭合。
