A scaffoldhopping approach was exploited to guide the discovery of a series of pyridine derivatives as novel cyclin‐dependent kinase (CDK2) inhibitors. These new compounds were designed, synthesized, and evaluated as CDK2 inhibitors. Most of the compounds showed potent inhibition against CDK2, and preliminary structure–activity relationship trends were revealed. A docking study on the most potent

the preparation of some new 4‐amino‐3,5‐dinitropyridine derivatives have been revealed. Nitration of 2‐chloropyridin‐4‐amine (1) as a starting material, in an unexpected one‐step reaction, to give dinitrated derivatives, followed by nucleophilic substitution reactions with sodium azide, potassium fluoride, ammonia, methylamine, and 4‐nitroimidazol, respectively, gave substituted 4‐amino‐3,5‐dinitropyridine
已经揭示了制备一些新的4-氨基-3,5-二硝基吡啶衍生物的简便合成途径。在意外的一步反应中硝化2-氯吡啶4-胺(1)作为起始原料,以生成二硝化的衍生物,然后与叠氮化钠,氟化钾,氨水,甲胺和4-硝基咪唑进行亲核取代反应分别得到取代的4-氨基-3,5-二硝基吡啶衍生物。同时,其叠氮化物衍生物进行了闭环转化为7-氨基-6-硝基[1,2,5]恶二唑并[3,4- b ]吡啶-1-氧化物。重要的是,所有亲核取代反应均在温和条件下进行。
