structural analogs of the antipodes of epibatidine (±)‐1, as well as the enantiomeric pairs (+)‐3/(−)‐3 and (+)‐4/(−)‐4 were synthesized and tested for binding affinity at α4β2 and α7 nicotinic acetylcholine receptor (nAChR) subtypes. Final derivatives were prepared through the condensation of racemic N‐Boc‐7‐azabicyclo[2.2.1]heptane‐2‐one (±)‐5 with the resolving agent (R)‐(+)‐2‐methyl‐2‐propanesulfinamide
盐酸Epiboxidine(+)- 2和(-)- 2,是Epibatidine(±)-1对映体的结构类似物,以及对映体对(+)- 3 /(-)- 3和(+合成了)-4 /(-)- 4,并测试了对α4β2和α7烟碱乙酰胆碱受体(nAChR)亚型的结合亲和力。通过将外消旋的N -Boc-7-氮杂双环[2.2.1]庚烷-2-一(±)-5与拆分剂缩合来制备最终衍生物(R)-(+)-2-甲基-2-丙烷亚磺酰胺。在三个新对映体对上进行的药理学分析证明,两种nAChRs亚型的对映体选择性总体上可忽略不计,这一结果与报道的相同受体亚型的天然和非天然依巴替丁对映体的报道相似。手性24:543-551,2012。分级为4 +©2012 Wiley Periodicals,Inc.
