We describe herein the synthesis of a late-stage intermediate en route to cortistatin A. Key transformations included a Snieckus-like cascade sequence culminating in a 6π-electrocyclization, an alkylative dearomatization, and the stereoselective functionalization of the cortistatin A-ring. While the total synthesis we sought was not accomplished, the work sets the stage for several approaches to the
我们在此描述了合成皮质抑素 A 的后期中间体。关键转化包括 Snieckus 样级联序列,最终形成 6π 电环化、烷基化脱芳构化和皮质抑素 A 环的立体选择性功能化。虽然我们寻求的全合成没有完成,但这项工作为通过转向全合成制备新型类似物的几种方法奠定了基础。
