chemical synthesis of sugar nucleotides requires a multistep procedure to ensure a selective reaction. Herein, sugar nucleotides were synthesized in one step using 2-chloro-1,3-dimethylimidazolinium chloride as the condensation reagent. The products were obtained in yields of 12–30%, and the yields were increased to 35–47% by the addition of a tuning reagent. NMR identification of the sugar nucleotides
