6-Amino-7-azaindole has been prepared by combination of diaminopyridine and diols by means of an acceptorless dehydrogenative condensation. In addition, amino pyridines may also yield towards pyrrolo[3,2-b]pyrrole systems. All of these transformation have been performed with accessible heterogeneous catalysts: Pd/C and ZnO.
6-Amino-7-azaindole 是由二氨基吡啶和二醇通过无受体脱氢缩合反应制备的。此外,氨基吡啶也可以生成吡咯并[3,2- b ]吡咯体系。所有这些转化都是使用可接近的多相催化剂进行的:Pd/C 和 ZnO。
