The organocatalytic enantioselective hydrophosphinylation of various secondary phosphine sulfides with aromatic and aliphatic nitroalkenes is presented in this study. The reaction produced chiral β-nitrophosphine sulfides with excellent yields and enantioselectivities (up to 99% yield and 99% ee). Furthermore, the chiral β-nitrophosphine sulfides can be easily converted into α-substituted β-aminophosphine, which is a family of useful P, N-ligands and phosphine catalysts.
Keywords: asymmetric hydrophosphinylation; organocatalysis; secondary phosphine sulfides; α-substituted β-aminophosphines.
