Original synthesis of 2-substituted-4,11-dimethoxy-1-(phenylsulfonyl)-2,3- dihydro-1H-naphtho[2,3-f]indole-5,10-diones using TDAE and Cu-catalyzed reaction strategy

We report herein an original and rapid synthesis of 2-substituted-4,11- dimethoxy-1-(phenylsulfonyl)-2,3-dihydro-1H-naphtho[2,3-f]indole-5,10-diones by TDAE mediated synthesis of N-benzylsulfonamides followed by an intramolecular N-arylation using Cu-catalyzed system.

Cyanuric chloride-catalyzed synthesis of N-sulfonyl imines

Cyanuric chloride is an inexpensive, efficient, and mild catalyst for the synthesis of N-sulfonyl imines by the reaction of sulfonamides with aryl aldehydes at 110°C under solvent-free conditions. This method affords the N-sulfonyl imines in short reactio
