A method is reported which appears to be general for the synthesis of 3-aryl and 3- alkylthietanes from the readily available aryl methyl and alkyl methyl ketones. The cycloaddition product of sulfene and the appropriate enamine is reduced to the desired 3- aryl-or 3-alkylthietane in three steps. Thietanes deuterated in the 01 position could be prepared by exchange under mild conditions at the sulfone stage. The oxidation of 3- ...
