The new 8-azapurin-6-ones 3 and the corresponding 8-azapurin-6-imines 4 are prepared by cyclocondensation of ethyl 5-acetylamino-1H-1,2,3-triazole-4-carboxylates 2 with amine hydrochlorides in the presence of phosphorus pentoxide and N,N-dimethylcyclohexylamine. A reaction pathway is proposed for the formation of 3 and 4. Various products 3 have been tested for fungicide activity.
新的8-氮杂嘌呤-6-酮3和相应的8-氮杂嘌呤-6-亚胺4是通过将5-乙酰氨基-1 H -1,2,3-三唑-4-羧酸乙酯2与胺的盐酸盐在环戊基中环缩合制备的。五氧化二磷和N,N-二甲基环己胺的存在。提出了形成3和4的反应途径。已经测试了各种产品3的杀真菌活性。
