J. Liu et al., CONFORMATION OF (RS)-O,O-(2,2'-BINAPHTHYL)-N-(ALPHA-BENZYLETHYL) PHOSPHAMIDATE AND (SS)-O,O-(2,2'-BINAPHTHYL)-N-(ALPHA-BENZYLETHYL) PHOSPHAMIDATE, Magnetic resonance in chemistry, 35(2), 1997, pp. 79-85
The conformations of (RS)- and (SS)-O,O-(2,2'-binaphthyl)-N-(alpha-ben
zylethyl) phosphamidate (binaphthol phosphamidate) were examined by me
ans of NMR, single-crystal x-ray diffraction and molecular mechanics c
alculations. There are physical and chemical differences between the t
wo diastereoisomers such as different abilities to form clathrates wit
h ethanol. These differences provide the theoretical basis for the res
olution of racemic binaphthol with optically active or-phenylethylamin
