The first total synthesis of (-)-spirangien A, a cytotoxic and antifungal polyketide of myxobacterial origin, is reported; this exploits a Stork-Wittig olefination and double Stille cross-coupling sequence to install the sensitive pentaene side chain onto a fully elaborated spiroacetal core, leading initially to the methyl ester of spirangien A.
据报道,首次合成了(-)-spirangienen A,这是一种源自粘杆菌的具有细胞毒性和抗真菌作用的聚酮化合物。这利用了Stork-Wittig烯化反应和双重Stille交叉偶联序列,将敏感的戊烯侧链安装在完全精制的螺缩醛核心上,最初生成了螺旋藻A的甲基酯。
