Abstract
When carboxylic acids beta-substituted by a tert-butoxy group were treated with thionyl chloride, an intermediate acyl chloride beta-substituted by a hydroxyl group was likely formed. Its subsequent intramolecular cyclization produced novel beta-lactones in one step. Two enantiomerically enriched la ctones could be prepared via intermediates obtained by enzymatic hydrolysis .
