One-pot, three-component condensation reaction between (phenylsulfonyl)acetonitrile, aromatic aldehydes, and 6-aminouracil for preparation of 6,8a-dihydropyrido[2,3-d]pyrimidine derivatives has been reported. The method involves domino Knoevenagel condensation/Michael addition, and cyclization cascade. The reaction was performed in glycerol which is commercially available, inexpensive and non-toxic
已经报道了(苯磺酰基)乙腈,芳族醛和6-氨基尿嘧啶的一锅三组分缩合反应,用于制备6,8a-二氢吡啶并[2,3- d ]嘧啶衍生物。该方法涉及多米诺Knoevenagel缩合/迈克尔加成和环化级联。该反应在甘油中进行,甘油是可商购的,廉价且无毒的化合物。产品的高纯度,极高的收率和广泛的底物是该方案的优点。
