conformationally rigid analogue of nicotine (2) or nornicotine (3) that showed high affinity for nicotinic acetylcholine receptors. Even though the synthesis and potent activity of this highly interesting compound was originally reported in 1986 (Kanne, D. B.; Ashworth, D. J.; Cheng, M. T.; Mutter, L. C.; Abood, L. G.

(+/-)-吡啶并[3,4-b]高碘烷[(+/-)-1]是尼古丁(2)或去甲烟碱(3)的构象刚性类似物,对烟碱型乙酰胆碱受体表现出高亲和力。即使这种高度有趣的化合物的合成和有效活性最初是在1986年报道的(Kanne,DB; Ashworth,DJ; Cheng,MT; Mutter,LC; Abood,LG)第一个高效桥连烟碱的合成9-Azabicylo [ 4.2.l] nona [2,3-c]吡啶(吡啶[3,4-b]高碘烷。J. Am。Chem。Soc。1986,108,7864-7865),尚未制备单独的光学异构体并研究了。在这项研究中,我们报告了(+)-和(-)-1的合成,并显示(+)-1在alpha4beta2 * nAChR处Ki = 1.29 nM,并且具有比(-)-1高260倍的亲和力。用于制备异构体的中间体的单晶X射线分析确定了绝对立体化学为(1S,6S)-(+)-1和
