A 9-step enantioselective total synthesis of both (+)-hyperforin and its pyran congener (+)-pyrohyperforin is described herein. The synthesis highlights a late-stage 1,3-diene diversification, including an abiotic cyclization cascade for pyran formation, and a selective 1,4-semihydrogenation of polyenes.
本文描述了 (+)-hyperforin 及其吡喃同源物 (+)-pyrohyperforin 的 9 步对映选择性全合成。该合成突出了后期的 1,3-二烯多样化,包括形成吡喃的非生物环化级联,以及多烯的选择性 1,4-半氢化。
