Fused pyrimidine cores are privileged kinase scaffolds, yet few examples of the 2-amino-pyrido[3,4-d]pyrimidine chemotype have been disclosed in the context of kinase inhibitor programs. Furthermore, no general synthetic route has been reported to access 2-amino-pyrido[3,4-d]pyrimidine derivatives. Here we report a versatile and efficient chemical approach to this class of molecules. Our strategy involves
融合的嘧啶核心是特殊的激酶支架,但在激酶抑制剂计划的背景下,很少有 2-氨基-吡啶并[3,4- d ]嘧啶化学型的例子被披露。此外,尚未报道获得 2-氨基-吡啶并[3,4- d ]嘧啶衍生物的通用合成路线。在这里,我们报告了一种针对此类分子的通用且有效的化学方法。我们的策略涉及8-氯-2-(甲硫基)吡啶并[3,4- d ]嘧啶中间体的简明制备及其有效衍生化,以得到具有激酶抑制剂潜力的新型化合物。
