Abstract

The Cu(OTf)(2) catalysed reaction of pyrrole with N-tosyl imines gives pyrrole sulfonamides in high yields. The addition reaction takes place regioselectively at C(2) of the pyrrole. The procedure is simple and does not require anhydrous conditions. (c) 2005 Elsevier Ltd. All rights reserved.
