An efficient and stereodefined process is described for the preparation of 2,3,4-trisubstituted tetrahydrofuran lignans, sesaminone and 4-epidihydrosesamin. The synthetic strategy is based on the similar chemoselective hydrogenation of functionalized lactol derivatives, elaborated through asymmetric condensation of a 4,5-trans-disubstituted lactone.
本研究描述了制备 2,3,4-三取代的四氢呋喃木脂素、芝麻素酮和 4-epidihydrosesamin 的高效立体定向工艺。该合成策略基于官能化内酯衍生物的类似化学选择性氢化,通过 4,5-反式二取代内酯的不对称缩合制备而成。
