Oxidation of substituted thietanes 1a, b, and 6 with m-chloroperoxybenzoic acid preferentially gives the corresponding cis-sulfoxides with modest diastereoselectivity. Selective oxidation of the trans over the cis diastereomeric pairs of sulfoxides 2a, 3a; 2b, 3b; 7, 8 occurs with moderate selectivity with m-chloroperoxybenzoic acid. The basis for these selectivities is hydrogen bonding between the 3-substituent and the peracid.
