Selective synthesis of C-arylglycosides via Cp*RuCl-catalyzed partially intramolecular cyclotrimerizations of C-alkynylglycosides.
In the presence of catalytic amounts of Cp*RuCl(cod), the partially intramolecular cyclotrimerizations of various C-alkynylglycosides and C-diynylglycosides proceeded at ambient temperature to afford C-arylglycosides.
