摘要: 本文采用吡唑并[3,4-d]-1,3-噁嗪-6-酮衍生物(Ⅰ)与伯胺反应,合成了1-烃基-5-取代苯甲酰胺基-4-吡唑(N-取代)甲酰胺(Ⅱ);由LiAlH4,对Ⅱ分子中2个酰胺基的选择性还原合成了1-烃基-5-取代氨基-4-吡唑(N-取代)甲酰胺(Ⅲ).共合成新化合物23个,通过1HNMR、13CNMR、MS、IR等证明了它们的化学结构,初步生物活性测定表明化合物Ⅱ具有一定的抗癌活性和农药活性。

Abstract: In order to look for biologically active heterocyclic compounds, pyrazolo[3,4-d]-1 ,3-oxazin-6-ones(Ⅱ) were reacted with primary amines, l-alkyl(or aryl)-5-benzoylamino-4-(N-alkyl carbamoyDpyrazole (Ⅱ) were obtained.By the reduction of Ⅱ, it was found for the first time that only one of the two amide groups in compound Ⅱ was reduced selectively to give 1-alkyl (or aryl)-5-substituted amino-4-(N-alkyl carbamoyl) pyrazole (Ⅲ).Twenty three new compounds were prepared and identified by 1H NMR,13C NMI,IRand MS.The preliminary biological activities of the products indicate that some of them possess antitumor and pesticidal activities.
