H. Hayakawa et al., A RIBONOLACTONE-BASED APPROACH TO THE SYNTHESIS OF 1'-CARBON-SUBSTITUTED THYMINE RIBONUCLEOSIDES, Nucleosides & nucleotides, 13(1-3), 1994, pp. 297-308
Thymine ribonucleosides bearing a carbon substituent at the anomeric p
osition were synthesized starting from D-ribonolactone by way of nucle
ophilic addition reaction of organolithium reagents and subsequent con
densation with trimethylsilylated thymine.
