Ty. Chau et al., SYNTHESIS AND STEREOSELECTIVE REDUCTION OF CHIRAL BETA-KETOSULFOXIDE FROM (-CAMPHOR()), Tetrahedron : asymmetry, 6(6), 1995, pp. 1221-1224
A chiral beta-ketosulfoxide derived from (+)-camphor was reduced with
different hydride reagents to afford chiral beta-hydroxysulfoxides in
excellent diastereo selectivities and yields.
