Herein, we describe a simple, four-step process for the preparation of 1,2,3-triazino[1,6- a]quinazolin-13-ones. This method involves ring-opening, quinazoline-forming condensation, reduction, diazotization accompanied by rapid intramolecular cyclization in the last step afforded the desired products with structurally complex heterocyclic core in excellent to high yields.
在这里,我们描述了一个简单的四步过程,用于制备1,2,3-三嗪[1,6-a]喹唑啉-13-酮。该方法包括开环,形成喹唑啉的缩合,还原,重氮化以及最后的快速分子内环化,从而以优异至高收率提供了具有结构复杂的杂环核的所需产物。
