【Abstract】 The title compound(+)-O-naphthyl cyclophosphorodiamidate(C 32H 35N 2O 2P, M r=510.59) has been synthesized and characterized by 31P NMR, 1H NMR and elemental analysis. X-ray diffraction analysis at 273(2) K indicates that the compound belongs to orthorhombic system, space group P2 12 12 1 with cell parameters: a=1.002 8(4) nm, b=1.140 6(4) nm, c=2.445 5(8) nm, V= 2.797 1(18) nm 3, Z=4, D c=1.212 g/cm 3, F(000)=1 088, μ=0.129 mm -1. The structure parameters were refined by full-matrix least-squares on F 2 to R=0.058 5 and wR=0.082 7. The flack x pamameter was 0.03(12). The absolute configuration of the phosphorus in the title compound is S.更多还原
