A chelator-type β-C-nucleoside having a catechol ligand as the nucleobase was found to form a stable 2 : 1 complex with trimethyl borate, which was characterized by 1H-NMR and electrospray ionization time-of-flight (ESI-TOF) mass spectroscopies. Both phosphoramidite and phosphoriester derivatives of this nucleoside were also prepared as synthetic precursors for DNA oligomer syntheses.
