The synthesis of 3 -aryl-N-n-propyl-piperidines is described in six steps starting from a-sulfonyl acetamide via the formal [3+3] cycloaddition reaction of the latter into glutarimide. The pathway involves an efficient cycloaddition and regioselective reduction, and yields useful building blocks for heterocyclic chemistry. (C) 2002 Elsevier Science Ltd. All rights reserved.
