The highly effective and enantioselective sulfenylation of β‐keto phosphonates catalyzed by α,α‐diaryl‐L‐prolinols has been developed. The optically active α‐sulfenylated β‐keto phosphonates could be obtained under mild reaction conditions in good yields (up to 92%) and with excellent enantioselectivities (up to 92% ee).
已开发出α,α-二芳基-L-脯氨醇催化的β-酮膦酸酯的高效对映选择性亚磺酰基。可以在温和的反应条件下以良好的收率(高达92%)和极好的对映选择性(高达92%ee)获得旋光性的α-亚磺酰基化的β-酮膦酸酯。
