Amination of allylic alcohols is an effective approach in the facile synthesis of N-allylic alkylation or N-alkylationamines. Recently, a series of catalysts were devised to push forward this transformation. However, current synthetic methods are typically limited to achieve either N-allylic alkylation or N-alkylation products via a certain catalyst. In this article, a pH-mediated selective synthesis of N-allylic

Ten N-(3-phenylpropyl)-N'-benzylpiperazines having different substituents on the benzyl moiety were synthesized and evaluated for sigma(1) and sigma(2) receptor binding. The sigma(1) affinities were 0.37-2.80 nM, sigma(2) affinities were 1.03-34.3 nM, and selectivities, as sigma(2)/sigma(1) affinity ratios, ranged from 1.4 to 52. Three compounds tested in a phenytoin shift binding assay profiled as probable a, antagonists. Quantitative structure-activity relationships depended on pi(x), MR or E-S and Hammett sigma values. The hydrophobicity term is negative for sigma(1) binding but positive for sigma(2) binding, indicating a major difference between the pharmacophores. (c) 2007 Elsevier Ltd. All rights reserved.
