Enantiomeric R-(−)-and (S)-(+)-2-anilino-2-oxo-1, 3, 2-oxazaphosphorinanes (1) have been synthesized by catalytic debenzylation of separated diastereomers of 3-(α-methylbenzyl)-2- anilino-2-oxo-1, 3, 2-oxazaphosphorinanes. Self-induced diastereomeric anisochronicity in non-racemic mixtures of these enantiomers was shown to vary with enantiomeric composition, overall specimen concentration, and temperature. The equilibrium constants ...
