Deprotection of α-imidazole/benzimidazole ribonucleosides by catalytic carbon tetrabromide initiated photolysis
摘要:
Several protected benzimidazole and imidazole alpha-ribonucleosides were deprotected in excellent yield Lit ambient temperature using CBr4 initiated photolysis in methanol at ambient temperature. No selectivity was observed and both trityl and isopropylidene groups were deprotected Under the reaction conditions. (c) 2005 Elsevier Ltd. All rights reserved.
