An 11-step total synthesis of the methyl ester of a potential metabolite of the autoxidatively formed natural product 15-E2-IsoP, whose metabolism is not known, is reported. Several vinylogous Mukaiyama aldol additions were tested for the assembly of the acyclic C7−C20 precursor. A new oxidative dianion cyclization served to access the cyclopentane core. The full carbon skeleton was synthesized by
据报道,其代谢未知的自氧化形成的天然产物15-E 2 -IsoP的潜在代谢产物的甲酯的11步全合成。测试了几种乙烯基Mukaiyama Aldol添加剂的无环C7-C20前体的组装。一种新的氧化双阴离子环化作用用于进入环戊烷核。通过乙炔基烷基化合成全碳骨架。对于最有效的途径,代谢物的总产率为1.4%。结果令人信服地证明,E 2 -IsoP代谢产物对差向异构体高度敏感,因此它们也可能有助于PGE 2-的作用和代谢。
