A concise synthesis of thioaurones via NBS-induced cyclization of MOM-protected 2′-mercaptochalcones†
Abstract
A mild and efficient approach for the synthesis of thioaurones via NBS-induced cyclization of methoxymethyl-protected mercapto-chalcones has been developed. This simple method is highly functional group tolerant and provides straightforward access to thioaurones in good to high yields.
