Efficient synthesis of the title compound, the first diastereomerically pure trifluoromethanesulfinic acidderivative (8), has been achieved by direct trifluoromethanesulfinylation of the lithiated (4R)-(−)-4-phenyloxazolidin-2-one; in contrast to the reaction between CF3S(O)Cl and (1R,2S,5R)-(−)-menthol which occurs with low stereoselectivity ( 98% de.
