A Na2HPO4-catalyzed four-component reaction between a ketone, malononitrile, S8 and formamide has been realized for the first time. This reaction provides a concise approach to thieno[2,3-d]pyrimidin-4-amines, previously requiring 5 steps. The utility of this reaction was validated by preparing a multi-targeted kinase inhibitor and an inhibitor of the NRF2 pathway with excellent atom- and step-economy
首次实现了Na2HPO4催化酮、丙二腈、S8和甲酰胺之间的四组分反应。该反应提供了一种制备噻吩并[2,3-d]嘧啶-4-胺的简洁方法,之前需要 5 个步骤。通过制备具有优异原子经济性和步骤经济性的多靶点激酶抑制剂和 NRF2 途径抑制剂,验证了该反应的实用性。
