The Sonogashira reaction of a resin-bound iodobenzoic acid with trimethylsilyl acetylene followed by TBAF desilylation provided a polymer-supported aryl acetylene, 3. Treatment of 3 with an aldehyde and a secondary amine in dioxane in the presence of CuCl catalyst results in the generation of resin-bound propargylamines. The final products (4) were cleaved from the resin and obtained in excellent yields and purity. (C) 1998 Elsevier Science Ltd. All rights reserved.
