Palladium-catalyzed decarboxylative methylthiolation of aromatic carboxylic acids by using DMSO as the sulfurizing reagent

By using simple and readily available DMSO as a convenient and environmentally friendly source of sulfur, a practical approach for the Pd-catalyzed decarboxylative methylthiolation of 2-nitrobenzoic acids was developed. A range of substituents on the aryl group of the ortho-nitrobenzoic acid were compatible with this process.

Copper-catalyzed decarboxylative methylthiolation of aromatic carboxylate salts with DMSO

A novel copper-catalyzed decarboxylative methylthiolation of arenecarboxylate salts has been realized using DMSO as the methylthiolation source. Various potassium aryl carboxylates underwent decarboxylative methylthiolation under air to furnish the corresponding aryl methyl thioethers in moderate to excellent yields. The reaction tolerated a wide variety of functional groups. Notably, the synthesis of ethylthioethers was also successfully achieved directly from diethyl sulfoxide under similar reaction conditions.

Synthesis and blood pressure lowering activity of 3-(substituted-amino)-1,2,4-benzothiadazine 1-oxide derivatives

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.
