A concise and highly divergent synthetic route has been developed to rapidly access 1,3,6-trisubstituted pyrazolopyrimidines. The synthesis features a microwave assisted one-pot N1-alkylation/Suzuki–Miyaura reaction as the key step. The sequence of the synthetic scheme can be varied to selectively modify the N1, C3, or C6 position at a late synthetic stage, thereby providing a highly efficient approach
已经开发出一种简洁且高度分歧的合成路线来快速获得1,3,6-三取代的吡唑并嘧啶。合成的关键步骤是微波辅助一锅N1-烷基化/ Suzuki-Miyaura反应。合成方案的顺序可以改变,以在合成后期选择性地修饰N1,C3或C6的位置,从而提供一种高效的方法来探索吡唑并嘧啶衍生物的结构-活性关系。这些反应的范围也已被探索。
