GKK1032s, novel antibiotic anti-tumor agents, was achieved via Mitsunobu reaction between a sterically congested indenol derivative and a p-substituted phenol derivative. The indenol derivative, the key substrate for the Mitsunobu reaction, was efficiently synthesized starting from the known indanone derivative through regio- and stereoselective methylation, Saegusa oxidation, and carbonyl transposition
GKK1032s 的烷基芳基醚部分(新型抗生素抗肿瘤剂)的对映选择性合成是通过空间拥挤的茚醇衍生物和对位取代的苯酚衍生物之间的光信反应实现的。茚醇衍生物是 Mitsunobu 反应的关键底物,从已知的茚满酮衍生物开始,通过区域和立体选择性甲基化、Saegusa 氧化和羰基转座作为关键步骤高效合成。
