A new, divergent, efficient, and selective synthesis of furo- and thieno[2,3-d]pyrimidin-4-amine derivatives by microwave irradiation has been developed starting from readily available amines and substituted 2-aminofuran-3-carbonitrile or 2-aminothiophene-3-carbonitrile, which are converted into corresponding formamidines in DMF using benzenesulfonyl chloride.
从容易获得的胺和取代的2-氨基呋喃-3-甲腈或2-氨基化合物开始,开发了一种新的,发散的,有效的,选择性的微波辐射合成呋喃并和噻吩并[2,3 - d ]嘧啶-4-胺的衍生物。 -氨基噻吩-3-腈,其在DMF中使用苯磺酰氯转化为相应的甲am。
