On September 29, 1992, Anderson, Rosaleen J.; Dixon, Ruth M.; Golding, Bernard T. published an article.Formula: C9H15IO4 The title of the article was Alkylcobalamins: formation by enantioselective alkylation of cob(I)alamin, proton NMR spectra, and conformational analysis of the alkyl group. And the article contained the following:
The 1H NMR spectra of a series of alkylcobalamins, principally 2-oxy substituted, including adenosyl- and ribosylcobalamin, were analyzed with particular attention to the conformation of the alkyl moiety. The enantioselectivity of formation of some of these compounds from their chiral precursors was determined (NMR anal.) and rationalized. The experimental process involved the reaction of (3aS,4S,6R,6aR)-4-(Iodomethyl)-6-methoxy-2,2-dimethyltetrahydrofuro[3,4-d][1,3]dioxole(cas: 38838-06-1).Formula: C9H15IO4
The Article related to isopropylideneribofuranoside reaction cobalamin, alkyloxirane alkylation cobalamin, dioxolane alkylation cobalamin, proton nmr alkylcobalamin, Organometallic and Organometalloidal Compounds: Group Viii – Co, Ni, Ru, Rh, Pd, Os, Ir, Pt and other aspects.Formula: C9H15IO4
