Organocatalytic enantioselective hydrophosphonylation of imines having the a heteroarenesulfonyl group afforded the respective products with high enantioselectivity. Both enantiomers of α-amino phosphonates were obtained by using different Cinchona alkaloids with up to 98% ee.
具有杂芳烃磺酰基的亚胺的有机催化对映选择性氢膦酰基化提供了具有高对映选择性的各个产物。通过使用具有高达98%ee的不同的Cinchona生物碱,可以得到两种α-氨基膦酸酯的对映体。
