Novel derivatives of 2-(1H-(bi)pyrazol-3-yl)phenols and 2-(1,4(5)-(benzo)diazepin-4-yl)phenols were obtained in the reaction of (4-amino-2H-chromen-2-ylidene)malondialdehyde and 4H-chromen-4-imines with 1,2-, 1,3-, and 1,4-dinucleophiles proceeding as a cascade reaction initiated by the Michael reaction.
在(4-氨基)反应中获得了2-(1 H-(双)吡唑-3-基)酚和2-(1,4(5)-(苯并)二氮杂-4--4-基)酚的新型衍生物作为由迈克尔反应引发的级联反应,进行了-2 H-铬-2-亚甲基)丙二醛和4 H-铬-4-亚胺与1,2-,1,3-和1,4-二亲核试剂的反应。
