An efficient solid-phase procedure for the synthesis of a number of 2-substituted piperidines is reported. Starting from solid-supported carbamate -tethered δ-amino acetals, 2- benzotriazolyl- substituted (Bt-substituted) piperidines were obtained by acid-induced ring-closure followed by trapping of the transient N-acyliminium ions with benzotriazole. These 2-Bt-substituted piperidines were then used as precursors for the successful introduction of several C-nucleophiles by N-acyliminium ion chemistry.
