本文以异嘌呤类杂环-吡唑并[3,4-d]嘧啶为先导,以1-取代-5-取代氨基-4-(N-烷基)吡唑甲酰胺及取代苯基二氯化膦、六乙基亚磷三酰胺为原料,设计并合成42个新型含氮磷杂并环化合物-吡唑并[3,4-d]-1,3,2-二氮磷杂六环-6-酮衍生物.经1H NMR、IR、MS及元素分析确定了它们的化学结构.初步测定了它们的生物活性.实验表明这些化合物具有一定的抗癌活性及农药活性. In this paper, an isopurine heterocycle-pyrazolo [3,4-d] pyrimidine is used as a precursor and substituted 1-substituted-5-substituted amino-4- (N-alkyl) pyrazolecarboxamides and substituted phenyl dichlorides Phosphine, hexaethylphosphoric triamide as raw materials, 42 novel nitrogen-containing phosphazenoid compounds were designed and synthesized - pyrazolo [3,4-d] -1,3,2-diazaphosphorinane 6-one derivatives, their chemical structures were confirmed by 1H NMR, IR, MS and elemental analysis. Their biological activities were initially determined. Experiments show that these compounds have certain anticancer activity and pesticidal activity.
