The development and mechanism of the highly chemo- and enantioselective organocatalytic hydrophosphination reaction of α,β-unsaturated aldehydes is presented. The reactions are catalyzed by protected chiral diarylprolinol derivatives and give access to optically active phosphine derivatives in high yields with up to 99% ee. The organocatalytic addition of other phosphorus nucleophiles was also investigated
提出了α,β-不饱和醛的高度化学和对映选择性有机催化加氢磷酸化反应的进展和机理。该反应由受保护的手性二芳基脯氨醇衍生物催化,并以高达99%ee的高产率获得旋光性膦衍生物。还研究了其他磷亲核试剂的有机催化加成。通过密度泛函理论计算研究了与二苯膦作为亲核试剂反应的高对映选择性的起源。
