The key steps in the synthesis of clavulactone are formation of an enantiopure cyclopentane precursor by epoxide rearrangement and intramolecular carbonyl–ene reaction, construction of the 3,4‐dihydro‐2H‐pyran ring by intermolecular hetero‐Diels–Alder reaction, closure of the eleven‐membered ring, and finally generation of the lactone functionality by chemoselective allylic C(sp3)H oxidation.
合成棒内酯的关键步骤是通过环氧化物重排和分子内羰基-烯反应形成对映体纯的环戊烷前体,通过分子间杂Diels-Alder反应构建3,4-二氢-2 H-吡喃环,闭环11元环,最后通过化学选择性烯丙基C(sp 3)H氧化生成内酯官能团。
