The stereoselective total synthesis of dinemasone A has been accomplished. The key reactions, Sharpless asymmetric epoxidation, lithium-mediated epoxy alcohol opening, and double-intramolecular hetero-Michael addition, gave access to dinemasone A from lactic acid esters. The stereochemistry at the spiro carbon was determined using extensive NMR studies.
已完成地尼马松A的立体选择性全合成。关键反应 Sharpless 不对称环氧化、锂介导的环氧醇开环和双分子内杂迈克尔加成,可以从乳酸酯中获得地尼松 A。使用广泛的 NMR 研究确定了螺碳的立体化学。
