Copper-catalyzeddecarboxylative thiolation using molecular oxygen as the sole oxidant was developed. A variety of aromaticcarboxylicacids including 2-nitrobenzoic acids, pentafluorobenzoic acid and several heteroaromatic carboxylicacids undergo efficient...

A series of (substituted amino)-1,2,4-benzothiadiazine 1-oxides has been synthesized and most members of the series have been shown to have blood pressure lowering effects in normotensive rabbits and in spontaneously hypertensive rats. The most active member of the series was 3-[4-(2-furoyl)-1-piperazinyl]-6,7-dimethoxy-1-methyl-1H-1,2,4-benzothiadiazine 1-oxide hydrochloride. This compound in animal tests was equipotent to the known antihypertensive Prazosin.

Transformation of aryl alcohols into high-value functionalized aromaticcompounds by selective cleavage and functionalization of the C(aryl)–C(OH) bond is of crucial importance, but very challenging by far. Herein, for the first time, we report a novel and versatile strategy for activation and functionalization of C(aryl)–C(OH) bonds by the cooperation of oxygenation and decarboxylative functionalization
