Several 1-substituted-7-alkyl-2-thioxopurines 8,9,10 were synthesized by the reaction of isothiocyanates with 1-alkyl-4-amino-5-cyanoimidazoles 3. Treatment of 3 with methyl isothiocyanate gave the Dimroth rearranged product 6-methylamino-7-alkyl-2-thioxopurines 11. The structure of 11 was unambiguously defined by X-ray crystallography.
通过异硫氰酸酯与1-烷基-4-氨基-5-氰基咪唑3的反应,合成了数个1-取代的-7-烷基-2-硫代嘌呤8,9,10。3用异硫氰酸甲酯处理得到Dimroth重排产物6-甲基氨基-7-烷基-2-硫氧杂嘌呤11。X射线晶体学明确地定义了11的结构。
