A general route to unsubstituted N-aryl and heteroarylaminobenzenesulfonamides
摘要:
Starting from suitably protected 3- and 4-aminobenzenesulfonamides, a practical two-step strategy for the synthesis of unsubstituted N-aryl and heteroarylaminobenzenesulfonamides was devised. Strong bases are tolerated during the N-arylation step. Overall moderate to excellent yields are reported. (C) 2011 Elsevier Ltd. All rights reserved.
