Abstract
Abstract An operationally simple and user-friendly process to access privileged scaffolds such as acids, amides and isothiazoles has been devised employing β-ketodithioesters for the first time. Remarkably, the new protocol involves combination of C C bond cleavage and C O/C N/N S bond formations in one-pot. Aqueous ammonia led to the formation of skeletally distinct amide and isothiazole, whereas aqueous NaOH enabled the formation of aromatic acid near quantitative yield. This practical approach, which can dramatically streamline the synthesis of simple molecules, is highly chemoselective, cost-effective, amenable to gram scale, insensitive to moisture as well as bears high functional group compatibility.
