Copper catalyzed three-component synthesis of benzothiazolones from o-iodoanilines, DMF, and potassium sulfide?
RSC Advances Pub Date: 2013-12-19 DOI: 10.1039/C3RA46803H
Abstract
A copper catalyzed three-component reaction was developed for the synthesis of benzothiazolones. In the presence of CuBr2, the reaction of o-iodoanilines and K2S with DMF proceeded smoothly and generated the corresponding benzothiazolones with good isolated yields. DMF functioned both as the carbon monoxide source and as the reaction medium in this reaction.
