optically active without employment of a chiral auxiliary. Their enantiomericexcesses were determined by esterification, conversion to diasterecomeric phosphonodithioates on reaction with-31CH3-POCl2, followed by integration of the well separated proton-decoupled P NMR signals. This is apparently the first example of enantiomeric excess determinations of chiral tertiary thiols.
