Efficient one-pot synthesis of 2,4-di(het)aryl and 2,4-diamino pyrido[3,2-d]pyrimidines involving regioselective SNAr and palladium-catalyzed reactions
An efficient and original synthesis of various 2,4-disubstituted pyrido[3,2-d]pyrimidines is reported. One-pot di(het)arylation and diamination approaches were used to obtain highly functionalized products in very good yields. The two one-pot processes were compared to their step-by-step related synthesis. Both routes started from 2,4-dichloropyrido[3,2-d]pyrimidine 1 and included a chlorine discrimination
报道了各种2,4-二取代的吡啶并[3,2- d ]嘧啶的有效且原始的合成。使用一锅二(杂)芳基化和胺化方法以非常高的收率获得高度官能化的产品。将这两个一锅法过程与其逐步相关的合成进行了比较。两种途径均从2,4-二氯吡啶并[3,2- d ]嘧啶1开始,并且在第一反应期间包括氯鉴别。
