Abstract

Optically active 1,3,2-oxathiaphosphorinanes (3) and (4) were prepared from (-)-10-mercaptoisoborneol (1) and phosphorus dichlorides [RP(X)Cl2] (2). The configuration at phosphorus in these derivatives was assigned on the basis of their 1H nmr spectral data and X-ray diffraction analysis of 4f.
