Nous dicrivons une rnCthode originale de phosphorylation du rnyo-inositol non protCgC, qui fournit plusieurs myo-inositol phosphates A la fois. Le schema reactionnel cornporte une phosphoranylation totale ou partielle du cyclitol, I'aide de l'arninobicyclophosphane 8, suivie d'une oxydation des bicyclophosphoranes liaison P-H obtenus et d'une hydrolyse acide des phosphates neutres qui en rCsultent. Dans le cas de la tris-phosphoranylation nous avons identifie, parmi les fractions sCparCes par HPLC, le myo-inositol-l,2(cycl) phosphate 22, le myo-inositol-1 phosphate 23 et le myo-inositol-2 phosphate 24.BRIGITTE DUTHU, DOURAID HOUALLA, and ROBERT WOLF. Can. J. Chem. 66, 2965Chem. 66, (1988. An original method for the phosphorylation of an unprotected myo-inositol is described, which yields several rnyo-inositol phosphates at the same time. The reaction proceeds via a partial or complete phosphoranylation of the cyclitol by means of the aminobicyclophosphane 8, followed by oxidation of the resulting bicyclophosphoranes bearing a P-H bond and acid hydrolysis of the neutral phosphates thus formed. In the case of the tris-phosphoranylation we identified, among the HPLC fractions, the myo-inositol-l,2-(cyc1)phosphate 22, the myo-inositol-1-phosphate 23, and the myo-inositol-2-phosphate 24.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
