aromatic substituted, and optically resolved derivatives were prepared and evaluated for anticholinergic, antihistaminic, and antidepressant activity. In particular, the target cis isomer 7a as predicted from the modelling studies appears to possess excellent atypical antidepressant activity. This activity resides in the (+)-S,S optical isomer 10, which has the same absolute configuration as (+)-mianserin
分子模型研究表明,顺式-1,3,4,6,7,11b-六氢-2-甲基-7-苯基-2H-吡嗪并[2,1-a]异喹啉(7a)的合成为刚性类似物非典型抗抑郁药米塞林。将2,2-二苯乙胺与氯乙酰氯酰化,得到氯乙酰胺(2)。在二甲苯中用P2O5将2环化,得到1-(氯甲基)-3,4-二氢-4-苯基异喹啉(3)。胺化3,然后还原,得到异构体(氨基甲基)四氢异喹啉(4a和5)。用草酸二乙酯处理4a,然后用硼烷还原二酰胺,得到7a。制备了各种N-取代的,芳族取代的和光学拆分的衍生物,并评估了其抗胆碱能,抗组胺和抗抑郁活性。特别是,根据建模研究预测,目标顺式异构体7a似乎具有出色的非典型抗抑郁活性。该活性存在于(+)-S,S旋光异构体10中,其具有与(+)-米安色林相同的绝对构型。
