  Oxidation and isomerism of thietane-containing heterocycles

  摘要：

  Oxidation of 6-methyl-1-(thiethan-3-yl)pyrimidine-2,4(1H,3H)-dione, 5(6)-nitro-1-(thiethan-3-yl)-benzimidazole, 2-methyl-4-nitro-1-(thiethan-3-yl)- and 5-bromo-2-methyl-4-nitro-1-(thiethan-3-yl)imidazoles was examined. Corresponding 1-oxothietan-3-yl- and 1,1-dioxothietan-3-yl derivatives were synthesized for the first time. Some factors affecting the quality of the final products and optimal conditions of the oxidation of thietanyl derivatives of pyrimidine-2,4(1H,3H)-dione, nitrobenzimidazole, and nitroimidazole were found. According to 1H NMR spectroscopy data, the obtained sulfoxides are mixtures of cis/trans isomers, the diastereomers ratio determined by the substituent at position 3 of thietane ring.
