to the development of central tolerance to opioids. The studies herein focus on the development of SAR for P-gp substrate activity in the meperidine series of compounds, and show that a meperidine analog of greater potency, N-phenylbutyl-N-normeperidine, has low activity as a P-gp substrate and has the potential to be utilized as a tool to study the contribution of P-gp to the development of central

N-Substituted 4-phenylpiperidines were readily synthesized by one-pot cyclization of diols with amines via bis-triflate intermediates. The new synthesis under mild conditions gave various N-substituted 4-phenylpiperidines in moderate to good yields.
