DIANION-BASED METHODOLOGY FOR THE PREPARATION OF 2,3-DISUBSTITUTED BUTYROLACTONES

Unsymmetrical coupling utilizing the reaction of acylsulfonamide dianions with alpha-iodocarboxylate salts followed by a sequence consisting of selective reduction of the carboxylic acid group, hydrolysis of the acylsulfonamide, and spontaneous ring closure affords 2,3-disubstituted butyrolactones.
