Chemical and biological effects of substitution of the 2-position of ring-expanded (‘fat’) nucleosides containing the imidazo[4,5-e][1,3]diazepine-4,8-dione ring system: The role of electronic and steric factors on glycosidic bond stability and anti-HCV activity

2-position. Deglycosylation and incomplete ring-closure of the intermediates were the major problems encountered with most other cases. The stability of glycosidic bonds was found to be dependent on several factors including, but not limited to, the electron-donating inductive effect of the 2-phenyl substituents and the temperature of the reactionmedium. The three target RENs ZP-110, ZP-121, and ZP-122
