title: Regioselective phenylcarbamoylation of hydroxy-groups of ribonucleosides with bis(tributyltin) oxide--phenyl isocyanate system.
abstract: Partial phenylcarbamoylation of ribonucleosides by means of bis(tributyltin) oxide--phenyl isocyanate system is described herein; the reaction was found to occur regioselectively to give the corresponding 5'-, 3'-, and 2'-O-phenylcarbamoyl derivatives due to the conditions used.
