Abstract
Abstract A simple, efficient synthesis of 2-(1,2-dithiolan-3-yl)acetic acid from Meldrum's acid, acrolein and thioacetic acid is described. The isopropyldene 2,4- bis (acetylthio)butane-1,1-dicarboxylate formed in the three-component, single container process, can be methanolized to the corresponding dimethyl ester and then hydrolyzed, oxidized to the disulfide and decarboxylated to 2-(1,2-dithiolan-3-yl)acetic acid. The acid can be converted by conventional reagents into a variety of amide derivatives.
