Isoguanosine () was synthesized by a one-pot reaction involving acondensation of 5-amino- 1-(β-D-ribofuranosyl)imidazole-4-carboxamide () with benzoyl isothiocyanate, treatment of the resulting thiourea derivative with DCC furnished 5-(N1-benzoylcarbamoyl)aminoimidazole- 4-carbonitrile () which was then annulated with ethanolic ammonia to afford isoguanosine in a 68% yield from .
异鸟苷()是通过一锅反应合成的,其中一锅反应涉及将5-氨基-1-(β-D-呋喃呋喃糖基)咪唑-4-羧酰胺()与苯甲酰基异硫氰酸酯缩合,然后用DCC修饰5-(-)生成的硫脲衍生物。然后将N 1-苯甲酰氨基甲酰基)氨基咪唑-4-腈()与乙醇氨水环化,得到异鸟苷,产率为68%。
