A number of N- and C-alkyl derivatives of selected guanine analogs have been synthesized as potential antiviral agents. n-Pentyl, n-hexyl and 6-hydroxyhexyl derivatives in the imidazo[1,2-α]-s-triazine, 9–11, imid-azo[1,2-α]pyrimidine, 13–17, and thiazolo[4,5-d]pyrimidine, 19–21, ring system have been prepared by the direct alkylation of the sodium salt of the appropriate aglycon with the respective
已合成了许多鸟嘌呤类似物的N-和C-烷基衍生物作为潜在的抗病毒剂。Ñ戊基,ñ -己基和咪唑并6-羟己基衍生物[1,2-α] -小号嗪,9-11,咪唑并[1,2-α]嘧啶,13-17,和噻唑并[通过将合适的糖苷配基的钠盐与相应的烷基溴化物直接烷基化,制得19-21的4,5- d ]嘧啶环系统。3-氨基-6-肼基-1,2,4-三嗪-5(4 H)-one(22)与己酸或庚酸的脱水偶联,以及反应产物的进一步闭环图24A和24B提供的Ñ戊基和Ñ 6-氨基-1,2,4-三唑并[3,4的己基衍生物˚F ] [1,2,4]三嗪8(7 ħ) -酮25A和分别为25b。3-氨基-6-氨基甲基-1,2,4-三嗪-5(4 H)-one(23)与庚酸的类似缩合,然后环环化,很容易得到2-氨基-7 - n-己基咪唑[5,1- f ] [1,2,4]三嗪-4(3 H)-一(25c)。用N-溴代琥珀酰亚胺溴化25c得到相
