Abstract This paper deals with two synthetic routes designed to yield carbon nucleosides. The C-nucleosides are compounds of potential antibiotic utility. The first approach, designed to yield 4-(2'-deoxyribofuranosyl )-1 ,2,3-triazole (1), consisted of silylation of methyl vinyl ketone (4) to give 2-trimethylsilylosy-l,3-butadiene (6), followed by a crossed aldol condensation with a heteroaromatic aldehyde to yield the aldol l. Epoxidation and cyclization of l was expected to yield the target molecule ~. The initial step, silylation of methyl vinyl ketone (4), was successful. Using model compounds the second step of the synthesis was attempted. Numerous attempts to condense (6) with 2-pyridinecarboxaldehyde …
