Assembly of the C(1−27) macrocyclic skeleton of rimocidinolide, the aglycone of (+)-rimocidin (1), has been achieved in convergent fashion. Key features of the synthetic strategy entail application of multicomponent Type I Anion Relay Chemistry (ARC), in conjunction with the SN2/SN2′ reaction manifolds of vinyl epoxides, both employing 2-substituted 1,3-dithianes to construct the C(1−19) carbon backbone
雷莫西丁内酯((+)-雷莫西丁 ( 1 ) 的糖苷配基)的 C(1−27) 大环骨架的组装已以收敛方式实现。该合成策略的主要特点是应用多组分 I 型阴离子中继化学 (ARC),结合乙烯基环氧化物的S N 2/S N 2' 反应流形,两者均采用 2-取代 1,3-二噻烷来构建C(1−19) 碳主链。具有全反式三烯的 C(20−27) 硼酸乙烯基酯与先进的 C(1−19) 乙烯基碘化物的 Yamaguchi 结合,然后通过 Suzuki−Miyaura 交叉偶联进行大环化,完成了 C(1− 27)利莫西内酯骨架。
