The highly chemoselective dimethyldioxirane oxidation of 2-substituted 2,3-dihydro-1,5-benzothiazepin-4(5H)-one (1) allows the synthesis of the corresponding sulfoxides (2) or sulfones (3) in good yields. The relative stereochemistry of the sulfoxides has been unequivocally determined by X-Ray and NMR methods. The high trans diastereoselectivity can be explained on the basis of steric control.
