Abstract

Abstract: The synthesis of a representative series of l-methyl-3, 5-disubstituted thiabenzene I- oxides (2) by the reaction of dimethyloxosulfonium methylide with 1, 3-disubstituted 2- propynones (1) is described. In several cases, the initially formed allylides (3) were isolated and converted to the 1-oxides (2) under basic as well as neutral conditions. Alkylation of the 1-oxide 2a on the S-methyl group was effected in stages cia generation of the anion and ...
