本文描述了头孢他汀 1 的对映选择性合成。该合成的关键步骤是独特的甲基选择性烯丙基氧化、甾醇在 C12 处的直接 C-H 羟基化、Au(I) 催化的 5-endo-dig 环化和动力学螺缩酮化。
This Article describes an enantioselective synthesis of cephalostatin 1. Key steps of this synthesis are a unique methyl group selective allylic oxidation, directed C-H hydroxylation of a sterol at C12, Au(I)-catalyzed 5-endo-dig cyclization, and a kinetic spiroketalization.
