Benzo[4,5]imidazo[2,1-a]phthalazines have been obtained from various o-nitrophenylhydrazines through different 2-(2-nitrophenyl)-1,2-dihydro-1-phthalazinones as intermediates using an elaborated advanced procedure. An activated chlorine atom in 2-nitrophenyl moiety of the latter is able to undergo nucleophilic substitution for secondary alicyclic amines yielding novel substituted phthalazinones. Their
苯并[4,5]咪唑基[ 2,1- a ]酞嗪已通过精心设计的先进方法,通过不同的2-(2-硝基苯基)-1,2-二氢-1-酞嗪酮作为中间体,从各种邻硝基苯肼中获得。后者的2-硝基苯基部分中的活化氯原子能够被亲脂取代成脂环族仲胺,从而产生新的取代的邻苯二氮酮。它们的一锅还原和环脱水反应生成了一系列新型取代的苯并[4,5]咪唑并[2,1- a ]邻苯二嗪。
