1,3,4,14b-Tetrahydro-2H,10H-pyrazino[1,2-α]pyrrolo[2,1-c] [1,4]benzodiazepines (1a-e) were synthesized to investigate their potential CNS activity. The key step in the synthesis was the formation of the 10,11-dihydro-5H-pyrrolo[2,1-c][1,4]benzodiazepine (13) by reduction and concomitant cyclization of the nitroketone (11). Biological evaluation of 1a-e revealed interesting properties for 1b (CGS 7525A)
合成了1,3,4,14b-四氢-2 H,10 H-吡嗪并[1,2-α]吡咯并[2,1-c] [1,4]苯并二氮杂((1a-e)以研究其潜在的中枢神经系统活动。合成中的关键步骤是通过还原和伴随的硝基酮(11)环化形成10,11-dihydro-5 H-吡咯并[2,1-c] [1,4]苯并二氮杂ze(13)。1a-e的生物学评估显示了1b(CGS 7525A)的有趣特性[2]。
