of uracil polyoxin C (UPOC) methyl ester using the Ugireaction is described. The four components employed in the Ugireaction are 2′,3′-isopropylidine-protected uridine-5′-aldehyde, 2,4-dimethoxybenzylamine, an isoxazolecarboxylic acid, and the convertibleisonitrile N-(2-[(tert-butyldimethylsilyl)oxy]methyl}phenyl)carbonitrile. Following the Ugireaction, treatment with HCl in MeOH achieves deprotection
