报道了邻硝基苄胺一步杂环化合成3-烷氧基-2H-吲唑的方法。硝基苯基的电子性质、R-1-官能化的苄基胺的空间和电子性质以及醇溶剂的性质影响该杂环化反应的效率(类似于40-90%)。
A one-step heterocyclization of o-nitrobenzylamines to 3-alkoxy-2H-indazoles is reported. The electronic nature of the nitrophenyl group, the steric and electronic nature of the R-1-functionalized benzylic amine, and the nature of the alcoholic solvent affect the efficiency of this heterocyclization reaction (similar to 40-90%).
