Abstract An easy access has been demonstrated for seven membered diazepines and a six membered quinoxaline. The reaction proceeds rapidly with low-cost and readily available chemicals at mild temperature and provides straight forward access to diazepines and quinoxaline. All final products are new and confirmed by spectral analysis and by single crystal X-ray analysis. Two crystal structures of the diazepines have very similar compositions, exhibit similar conformations where four condensed and coplanar rings are placed in the same orientation to the rest of molecule.

新七元杂环的合成：轻松获得茚-苯并[1,4]二氮杂

摘要 七元二氮卓类药物和六元喹喔啉已被证明可轻松获取。该反应使用低成本且易于获得的化学品在温和的温度下快速进行，并提供直接获得二氮杂和喹喔啉的途径。所有最终产品都是全新的，并通过光谱分析和单晶 X 射线分析确认。二氮杂的两种晶体结构具有非常相似的组成，表现出相似的构象，其中四个稠合和共面的环与分子的其余部分以相同的方向放置。
