Rapid asymmetric access to b-hydroxysulfinic acids and allylsulfonic acids by chemoselective reduction of b-sultones.

[摘要]：The redn. of readily available optically active b-sultones bearing a b-trichloromethyl substituent proceeds chemoselectively at 3 different sites via C-Cl, C-O, or S-O bond cleavage and allows for the formation of highly enantioenriched b-hydroxy sulfinates and allylsulfonates.
