A novel approach for the visible-light-initiated synthesis of 2-amino-4H-pyran-3,5-dicarbonitrile derivatives via a one-pot, three-component reaction of aldehydes or isatins, malononitrile, and α-cyano ketones has been developed. The reaction was carried out at room temperature in ethanol/water to give the corresponding products with a wide range of functional groups in high yields. This process did
通过醛或靛红,丙二腈和α-氰基酮的一锅三组分反应,由可见光引发的合成2-氨基-4 H-吡喃-3,5-二碳腈衍生物的新方法有已开发。该反应在室温下在乙醇/水中进行,以高收率得到具有广泛官能团的相应产物。该过程不需要任何添加剂或色谱分离,可用于克级合成。
