achieved from cyclobutone and isobutyraldehyde through an 11-step synthetic route. During the work, a tandem Castro-Stephens coupling/1, 3-acyloxy shift/cyclization/semipinacol rearrangement sequence, which was developed recently by the same group, was used as the key step to build the crucial spirocyclic intermediate 5b.
通过 11 步合成路线,从环丁酮和异丁醛中获得了一种独特的 (±)-erythrodiene 和 (±)-spirojatamol 合成策略。在这项工作中,由同一小组最近开发的串联 Castro-Stephens 偶联/1, 3-酰氧基转移/环化/半哌啶醇重排序列被用作构建关键的螺环中间体5b的关键步骤。
