  Synthesis of Chiral 1-[ω-(4-Chlorophenoxy)alkyl]-4-methylpiperidines and Their Biological Evaluation at σ₁, σ₂, and Sterol Δ₈−Δ₇ Isomerase Sites

  摘要：

  Sumitomo's patented sigma ligand 1-[3-(4-chlorophenoxy)propyll-4-methylpiperidine (15), which has been claimed as agent for CNS disorders and neuropathies, and its lower homologue 12 were prepared along with related chiral (4-chlorophenoxy)alkylpiperidines. They were tested at sigma(1), sigma(2), and sterol Delta(8)-Delta(7) isomerase (SI) sites by in vitro radioligand binding assays, to evaluate the influence of a chiral center in the alkyl chain on the selective a, binding relative to other a family sites. Generally high alpha(1)-site affinities were found, so that the chirality introduced by a methyl substitution resulted in slight differences. Nevertheless, the shorter oxyethylenic chain was beneficial to increase a, selectivity. However, the (-)-(S)-4-methyl-1-[2-(4-chlorophenoxy)1-methylethyl]piperidine ((-)-(S)-17) reached the highest sigma(1) affinity (K-i = 0.34 nM) and the best selectivity relative to the sigma(2) site (547-fold). Compound (-)-(S)-17 displayed also a moderate selectivity (11-fold) relative to the SI site.

  insertion reactions of α-diazo esters. The reactivities and enantioselectivities of Cu complexes of the synthesized bisoxazoline ligands were lower than those of ligands without central chirality. However, planar chiral [2.2]paracyclophane-based bisoxazoline ligands with an inserted benzene spacer that had a sterically demanding isopropyl substituent showed good enantioselectivities in inter- and intramolecular
