TABLE 1.
I, sulfide; II, sulfoxide.
b Isolated yield of product.
c The enantioselectivity was determined by HPLC. The formula for ee is ([S] − [R]/[S] + [R]) × 100%, where [S] and [R] denote the concentrations of (S)- and (R)-PMSO, respectively. Absolute configurations (config.) were assigned by comparison of the specific rotations with the literature values.
d —, no configuration specified.
