A simple and efficient method has been developed for construction of sulfonylated quinolines via coupling of haloquinolines and sulfonylchlorides in water. The present methodology provides an attractive approach to various sulfonylated quinolines in moderate to good yields with favorable functional group tolerance, which has the advantages of operation simplicity, readily available starting materials
A practical and environment-friendly methodology for the construction of sulfonyl quinolines throughball milling promoted coupling of haloquinolines with sulfonic acid under metal-, base-, solvent- and additive-free conditions was developed.
