摘要
New synthetic methods for pyrimidine ring-expanded xanthosine, guanosine, and inosine analogues containing imidazo[4,5-e][1,4]diazepine nucleus are described. Treatment of N-1-substituted inosine derivatives 5, 12, 19 with aqueous NaOH gave 5-amino-4-(N-substituted carbamoyl)imidazole derivatives, followed by appropriate manipulations to cyclize these to constitute imidazo[4,5-e][1,4]diazepine nucleosides 11, 17, 22.
