ChemInform Abstract
Careful bromination of the readily prepared thiazolidinones (III) results in regioselective formation of the vinyl bromides (IV)/(V). However, at prolonged reaction times (III) are directly converted to the dienic derivatives (VI)/(VII) without isolation of intermediate bromides.
