Abstract One-pot, three-component condensation reaction between (phenylsulfonyl)acetonitrile, aromatic aldehydes, and α-naphthol for preparation of 4-(aryl)-3-(phenylsulfonyl)-4H-benzo[h]chromen-2-amine derivatives has been reported. The method involves domino Knoevenagel condensation/Michael addition, and cyclization cascade. The reaction was performed in glycerol, which is a commercially available
摘要 (苯磺酰基)乙腈,芳香醛与α-萘酚的一锅三组分缩合反应,用于制备4-(芳基)-3-(苯磺酰基)-4 H-苯并[ h ]铬-2-胺衍生物已经被报告了。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,甘油是一种可商购的,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。 图形概要
