  • Title: Dibutyltin oxide--phenyl isocyanate system for regioselective phenylcarbamoylation of the hydroxy-groups of ribonucleosides.
    Author: Ishido Y, Hirao I, Itoh K, Tamaki K, Araki Y.
    Journal: Nucleic Acids Symp Ser; 1980; (8):s7-8. PubMed ID: 7255200.
    Abstract:
    For partial phenylcarbamoylation of the hydroxy-groups of ribonucleosides, dibutyltin oxide--phenyl isocyanate system was found to be surperior to the bis(tributyltin) oxide--phenyl isocyanate system from the standpoint of reaction procedures including isolation of the products; the reaction was proved to occur with similar regioselectivity and to give the corresponding 5'-, 3'-, and 2'-O-phenylcarbamoyl derivatives in good yields, respectively, due to the conditions used.
