Dynamic kinetic resolution driven, asymmetric transfer hydrogenation of 4-substituted cyclic sulfamidate imine-5-phosphonates produces the corresponding cyclic sulfamidate-5-phosphonates. The process employs a HCO2H/Et3N mixture as the hydrogen source and the chiral Rh catalysts, (R,R)- or (S,S)-Cp?RhCl(TsDPEN), and it takes place at room temperature within 1 h with high yields and high levels of stereoselectivity.
