Abstract
The reaction between o-phenylenediamines, dehydroacetic acid and aromatic aldehydes is shown to give not only the expected 1,5-benzodiazepine derivative but also a 3,4-dihydroquinoxaline, the structure of which was determined by its 1H and 13C 1D and 2D NMR spectra.
摘要
邻苯二胺、脱氢乙酸与芳香醛之间的反应表明，不仅生成了预期的1,5-苯并二氮杂䓬衍生物，还生成了一种3,4-二氢喹喔啉，其结构通过1H和13C一维及二维核磁共振谱确定。
