asymmetric total synthesis of (–)-pterosin N from the N,N-diisopropyl-10-camphorsulfonamide-derived chiral 1,3-dioxolanone 11 has been accomplished in 9 steps with 8 % overall yield. The key steps in this synthesis were the highly stereoselective propargylation of 1,3-dioxolanone 11 to construct the chiral tertiary alcohol moiety, construction of a diene-ynone by Stille coupling, and an intramolecular Diels–Alder
从 N,N-二异丙基-10-樟脑磺酰胺衍生的手性 1,3-二氧戊环酮 11 第一次不对称全合成 (-)-pterosin N 已分 9 个步骤完成,总产率为 8%。该合成的关键步骤是 1,3-二氧戊环酮 11 的高度立体选择性炔丙基化以构建手性叔醇部分,通过 Stille 偶联构建二烯-炔酮,以及分子内 Diels-Alder 反应,然后进行芳构化以完成合成.
