The total synthesis of cytotoxic polyketides myceliothermophins E (1), C (2), and D (3) through a cascade‐based cyclization to form the trans‐fused decalin system is described. The convergent synthesis delivered all three natural products through late‐stage divergence and facilitated unambiguous C21 structural assignments for 2 and 3 through X‐ray crystallographic analysis, which revealed an interesting
描述了细胞毒性聚酮类菌丝体热蛋白 E ( 1 )、C ( 2 ) 和 D ( 3 ) 通过级联环化的全合成,以形成输血的十氢化萘系统。会聚合成通过后期发散提供了所有三种天然产物,并通过 X 射线晶体学分析促进了2和3 的明确 C21 结构分配,这揭示了其对映体形式之间有趣的二聚体结构。
