New 14-(Aryl)-14H-naphto[2,1-b]pyrano[3,2-e][1,2,4]triazolo[1,5-c]pyrimidine-2-acetonitriles have been prepared.
The chemical behaviour of these compounds was studied towards Knoevenagel condensation with salicylaldelyde
derivatives, thus, a series of 2-(coumarin-3’’-yl)-14(Aryl)-14H-naphto[2,1-b]pyrano[3,2-e][1,2,4]triazolo[1,5-
c]pyrimidines was obtain-ed. Their structures were characterized with IR, ES-HR-MS, 1H NMR and 13C NMR.
制备了新的14-(芳基)-14H-萘基[2,1-b]吡喃并[3,2-e][1,2,4]三唑并[1,5-c]嘧啶-2-乙腈。
研究了这些化合物与水杨醛的 Knoevenagel 缩合的化学行为
衍生物,因此,一系列 2-(香豆素-3''-基)-14(芳基)-14H-萘基[2,1-b]吡喃并[3,2-e][1,2,4]三唑并[1,5-
获得c]嘧啶。通过IR、ES-HR-MS、1H NMR和13C NMR对其结构进行了表征。
