Abstract
The highly chemoselective dimethyldioxirane oxidation of 2-substituted 2,3- dihydro-1,5-benzothiazepin-4(5H)-one (1) allows the synthesis of the corres ponding sulfoxides (2) or sulfones (3) in good yields. The relative stereoc hemistry of the sulfoxides has been unequivocally determined by X-Ray and N MR methods. The high trans diastereoselectivity can be explained on the bas is of steric control.
