  Condensation reactions of guanidines with bis-electrophiles: formation of highly nitrogenous heterocycles

  摘要：

  2-Amino-1,4-dihydropyrimidines were reacted with bis-electrophiles to produce novel fused bipyrimidine, pyrimidoaminotriazine, and pyrimidosulfonamide scaffolds. In addition, a quinazoline library was constructed using a guanidine Atwal-Biginelli reaction with 1-(quinazolin-2-yl)guanidines. The product heterocycles have novel constitutions with high nitrogen atom counts and represent valuable additions to screening libraries for the discovery of new modulators of biological targets.

  A practical and general method for the Biginelli cyclocondensation of guanidine with aldehydes and β-dicarbonyl compounds is described and illustrated with the synthesis of a set of 26 functionalized 2-amino-3,4-dihydropyrimidines. The simple protocol involves the ­microwave-mediated reaction of a twofold excess of guanidine hydrochloride with the required reaction partners in an alcohol at 120 °C

  用一组 26 个功能化的 2-氨基-3,4-二氢嘧啶的合成描述和说明了胍与醛和 β-二羰基化合物的 Biginelli 环缩合反应的实用和通用方法。简单的协议涉及双倍过量的盐酸胍与所需的反应伙伴在 120 °C 的酒精中的微波介导反应。收率通常良好，反应时间短，后处理简单。其范围比在常规加热下进行的类似反应要广泛得多。
