Catalytic application of N,2-dibromo-6-chloro-3,4-dihydro-2H-benzo[e][1,2,4]thiadiazine-7-sulfonamide 1,1-dioxide on the synthesis of 1-carbamato-alkyl-2-naphthols and 1-thioamido-alkyl-2-naphthols

Abstract

A novel N-bromo sulfonamide reagent, namely N, 2-dibromo-6-chloro-3,4-dihydro-2H-benzo[e][1,2,4]thiadiazine-7-sulfonamide 1,1-dioxide, is prepared and employed as a new and highly efficient catalyst for the preparation of 1-carbamato-alkyl-2-naphthol and 1-thioamido-alkyl-2-naphthol derivatives.
