采用芳香胺的Mannich碱亚硝化后再还原、环化的方法制备了3个吡唑类(Ⅳ_(a~c))和11个吡唑啉类(Ⅱ_(a~k))化合物,其中9个是未见报导的新化合物。所有化合物经红外、元素分析确证,对部分化合物的核磁、质谱作了报导。
Three compounds of pyrazole (Ⅳ_ (a ~ c)) and 11 pyrazolines (Ⅱ_ (a ~ k)) were prepared by nitrosation followed by reduction and cyclization of Mannich base of aromatic amines. Among them, 9 A new compound has not been reported. All the compounds were confirmed by IR and elemental analysis, and the NMR and MS spectra of some compounds were reported.
