Synthesis of {[A15-13C]5?-deoxy-N1-methyladenosylcobalamin+}Cl?
摘要:
The synthesis of {[A15-C-13] 5'-deoxy-N1-methyladenosylcobalamin(+)}Cl-, an analog of coenzyme B-12, was accomplished by glycosidation of [5-C-13]D-ribose with 4-pentenol, followed by benzoylation, coupling to N-6-benzoylaminopurine, deprotection, chlorination at C5', methylation at N1, and oxidative addition to reduced cobalamin. The alpha and beta anomers of the intermediate pent-4-enyl-erythro-furanosides were detected and quantified for the first time.
