The reaction of 6-hydrazino uracils 1 and nitrones 2 result in an efficient one-pot synthesis of pyrazolo[3,4-d]pyrimidines 3 in excellent yields. The isolation of the by-product aniline from the reaction mixture supported the plausible mechanism for the formation of pyrazolo[3,4-d]pyrimidines.
6-肼基尿嘧啶1和硝酮2的反应可有效地一锅合成吡唑并[3,4- d ]嘧啶3,产率极高。从反应混合物中分离出副产物苯胺支持了吡唑并[3,4- d ]嘧啶形成的合理机理。
