The first catalytic enantioselective Abramov reaction is described. The process is based on the utilization of a chiral disulfonimide catalyst, which efficiently avoids the difficulties encountered with metal‐based catalysts. Several functionalized α‐hydroxy phosphonates were synthesized in good yields and with excellent enantiomeric ratios of up to >99:1. The process was shown to be scalable and up
描述了第一催化对映选择性阿布拉莫夫反应。该工艺基于手性二磺酰亚胺催化剂的利用,可有效避免金属基催化剂遇到的困难。合成了几种功能化的α-羟基膦酸酯,收率高,对映体比例高达> 99:1。该方法显示出可扩展性,并且在温和的反应条件下可以使用多达1 g的原料。
