GRAPHICAL ABSTRACT
ABSTRACT
A novel synthetic approach is presented, involving unsaturated nucleoside hydroboration, with protected stavudine catalytically boronated with pinacolborane to several pinacolborane derivatives of stavudine or 2’,3’-dideoxythymidine. The products were converted to much more stable trifluoroborate derivatives that may be considered trifluoroboron analogues of nucleoside phosphates. The post-reaction mixture contained four isomers, being products of catalytic hydroboration, and two isomers, resulting from dehydrogenative borylation, each containing unsaturated 2’,3’-moiety. The new compounds were analyzed with NMR and LDI-HRMS methods.
