AN EFFECTIVE METHOD FOR THE PREPARATION OF O6-SUBSTITUTED GUANOSINE AND N3-SUBSTITUTED URIDINE DERIVATIVES VIA THE CORRESPONDING STANNYLATED INTERMEDIATES

Article abstract of DOI:10.1016/S0040-4039(00)84907-2

O⁶-substituted guanosine and N³-substituted uridine derivatives were obtained in high yields by stannylation of the corresponding unsubstituted nucleosides with bis(tributyltin)-oxide followed by treatment with various electrophiles.
