The Michael addition of dialkyl phosphites to nitroalkenes in the presence of heterobimetallic (S)-(−)-aluminum lithium bis(binaphthoxide), ALB, complex provided β-nitrophosphonates, precursors to β-aminophosphonic acids, in good to excellent enantioselectivities.
在异双金属(S)-(-)-铝双(二萘氧基氧化物)铝(ALB)的存在下,亚磷酸二烷基酯的迈克尔加成到硝基烯烃中,提供了β-硝基膦酸酯,β-氨基膦酸的前体,具有出色的对映选择性。
