synthetic protocol is a good alternative for the synthesis of latanoprost with high stereo selectivity and improved yield. A simple, convenient and convergent approach for the synthesis of (15R) latanoprost is reported with high stereo selectivity and improved yield from chiral precursor Corey lactone diol using Swern oxidation, allylic reduction and Wittig reaction conditions.
开发了一种有效的不对称合成途径,用于在Swern氧化,烯丙基还原和Wittig反应条件下,以Corey内酯二醇为手性底物,合成抗青光眼剂(15R)-拉坦前列素。在该方法中,使用甲醇中的低成本催化剂NiCl 2 / NaBH 4一步即可完成酮基和烯烃官能团的还原。该新的合成方案是合成具有高立体选择性和提高收率的拉坦前列素的良好选择。 据报道,使用Swern氧化,烯丙基还原和Wittig反应条件,从手性前体Corey内酯二醇合成立体(15R)拉坦前列素具有简便,便捷和收敛的方法,其立体选择性高,产率提高。
