| Abstract: | The title compound(+)-O-naphthyl cyclophosphorodiamidate(C32H35N2O2P, Mr=510.59) has been synthesized and characterized by 31PNMR, 1HNMR and elemental analysis.X-ray diffraction analysis at 273(2) Kindicates that the compound belongs to orthorhombic system, space group P212121with cell parameters: a=1.0028(4) nm, b=1.1406(4) nm, c=2.4455(8) nm, V= 2.7971(18) nm3, Z=4, Dc=1.212 g/cm3, F(000)=1088, μ=0.129 mm-1. The structure parameters were refined by full-matrix least-squares on F2to R=0.0585 and wR=0.0827. The flack x pamameter was 0.03(12).The absolute configuration of the phosphoruSIn the title compound is S. |
