A convergent route to 5-(arylsulfanyl)-6-sulfonamido-3-benzofuranones

Bosch, Joan,Roca, Tomàs,Catena, Juan-Lorenzo,Farrerons, Carles,Miquel, Ignasi

, p. 721 - 725 (2007/10/03)

A procedure for the synthesis of 5-(arylsulfanyl)-2,3-dihydro-6- sulfonamido-3-benzofuranones (1) via 5-bromo-3-methoxy-6-nitrobenzofuran (4) as a common advanced synthetic intermediate has been developed. The key step consists of a regioselective nucleophilic aromatic substitution of the bromine atom of 4 by an aryl or heteroarylthiol.
