Some 1,2,4-triazolo[1,5-a]pyrimidin-5-one derivatives 1 and their alicyclic condensed ring analogues 2-3 were converted through the corresponding “imino chlorides” 4-6 to the oximes 7-9. The “E” isomeric structure of the products obtained was proven with the use of cmr using the spectral data of the corresponding “benzyloximino” derivatives 10-12 prepared as model compounds.
一些1,2,4-三唑并[1,5- a ]嘧啶-5-酮衍生物1及其脂环式稠环类似物2-3通过相应的“亚氨基氯化物” 4-6转化为肟7-9。使用相应的作为模型化合物制备的“苄基肟基”衍生物10-12的光谱数据,使用cmr证明了所获得产品的“ E ”异构体结构。
