convenient procedure for the synthesis of olefins by the reaction of stabilized, semistabilized, and nonstabilized phosphorous ylides with various aldehydes or ketone using Amberlite resin as a mild base is described. Our developed method offers facile and racemization-free synthesis of α,β-unsaturated amino esters and chiral allylic amine. The developed methodology offers mild reaction conditions, high efficiency
摘要描述了使用 Amberlite 树脂作为弱碱,通过稳定、半稳定和不稳定的磷叶立德与各种醛或酮反应合成烯烃的简便方法。我们开发的方法提供了 α,β-不饱和氨基酯和手性烯丙胺的简便且无外消旋的合成。所开发的方法提供温和的反应条件、高效率和最终产品的容易分离,是已知程序的实用替代方案。图形概要
