A new strategy for the synthesis of the eight-membered heterocyclic skeleton of tetrahydro-quinazolino[3,2-c][2,3]benzodiazocin-15-ones, based on the Pictet–Spengler reaction of 3-amino-2-[2-(3,4-dimethoxyphenyl)ethyl]quinazolin-4(3H)-one with carbonyl compounds in acidic media, is proposed.
基于3-氨基-2- [Pictet-Spengler反应]合成四氢喹唑啉并[3,2-c] [2,3]苯并重氮酮-15-酮的八元杂环骨架的新策略提出了在酸性介质中具有羰基化合物的2-(3,4-二甲氧基苯基)乙基]喹唑啉-4(3 H)-one。
