The macrotricyclic part of roseophilin, a novel cytotoxic antibiotic, was efficiently synthesized starting with the known 3-formylpyrrole; the method features intramolecular alkylation to form the desired thirteenmembered carbocycle and base-induced intramolecular acylation to construct the requisite pyrrole-fused cyclopentanone ring system as the key steps.
从已知的3-甲酰基吡咯开始,有效合成了一种新的细胞毒性抗生素-玫瑰果蛋白的大三环部分。该方法的特征是分子内烷基化形成所需的十三元碳环,以及碱基诱导的分子内酰化,以构建必要的吡咯稠合的环戊酮环系统作为关键步骤。
