A new series of heterocyclic systems, including azole, azolopyrimidine, and pyridopyrimidine derivatives, attached to 2H-chromene scaffold, was prepared by a convenient procedure through the reactions of (E)-2-dimethylamino-methylene chromanone with different nitrogen binucleophiles. Various substituted chromeno[4,3-b]pyridine derivatives were also prepared through the reactions of (E)-2-dimethylaminomethylene
通过(E)-2-二甲基氨基-亚甲基苯并二氢吡喃酮与不同的氮双亲核试剂反应,通过方便的步骤制备了一系列新的杂环系统,包括与2 H-亚甲基支架相连的唑,氮杂嘧啶和吡啶嘧啶衍生物。通过(E)-2-二甲基氨基亚甲基苯并二氢吡喃苯并二氢吡喃酮与一系列活性亚甲基化合物的反应,还制备了各种取代的铬诺[4,3- b ]吡啶衍生物。
