asymmetric synthesis using chiral (R)-alpha-methylbenzylamine. All analogs were evaluated in the in vitro 5-HT1A and D2 binding assays and selected analogs were investigated further in biochemical and behavioral tests. Analogs with 9-methoxy substitution (R1 in 3) showed mixed 5-HT1A agonist and dopamine antagonist activities whereas the corresponding 9-hydroxy analogs displayed selective 5-HT1A agonist
描述了2,3,3a,4,5,9b-六氢-1H-苯并[e]吲哚衍生物(3)的合成和构效关系(SAR)。这些化合物是2-氨基四氢萘的构象受限的角三环类似物。由相应的2-四氢萘酮在几个步骤中完成合成。顺式类似物的对映异构体是由二对甲苯甲酰基-L-(或D)-酒石酸的非对映异构体盐的分步重结晶或使用手性(R)-α-甲基苄基胺的不对称合成获得的。在体外5-HT1A和D2结合试验中评估了所有类似物,并在生化和行为测试中进一步研究了所选类似物。具有9-甲氧基取代的类似物(R1在3中)显示出5-HT1A激动剂和多巴胺拮抗剂的混合活性,而相应的9-羟基类似物则具有选择性的5-HT1A激动剂活性。发现顺式类似物比相应的反式类似物更有效,并且在顺式系列中,(3aR)-(-)-对映异构体显示出更高的效力。用正丙基或烯丙基进行的氮取代(3中的R2)产生相似的活性,而用庞大的α-甲基苄基取代则导致活性降低。没有芳香取代基的类似物(3中的R1
