9b-hexahydro-3H-benz[e]indoles. The stereochemistry was confirmed by single-crystal X-ray analysis. In the 6-hydroxy series, the binding affinity at D1 and D2 receptors was of the order 22 (N-n-butyl) > 21 (N-n-propyl) > 23 (N-H). The compounds demonstrated greater binding affinity at D2 receptors than at D1 binding sites. In contrast, 8-OH derivatives exhibited affinity only for D2 receptors, with 25 (N-n-butyl)
合成了顺式1,2,3a,4,5,9b-六氢-3H-苯并[e]吲哚并评估了其对多巴胺D1和D2受体的结合亲和力。通过还原对空气敏感的三环烯胺10-14,可以容易地制备目标化合物21-25。用硼氢化钠,氰基硼氢化钠,乙醇中的碳载钯和乙醇或乙酸中的氧化铂还原10-14,仅得到顺式(3a,9b)1,2,3a,4,5,9b-六氢-3H -苯并[e]吲哚。通过单晶X射线分析证实了立体化学。在6-羟基系列中,在D1和D2受体上的结合亲和力为22(Nn-丁基)> 21(Nn-丙基)> 23(NH)。该化合物对D2受体的结合亲和力大于对D1结合位点的结合亲和力。相反,8-OH衍生物仅表现出对D2受体的亲和力,
