An efficient reaction route towards the new class of N,O-psiconucleosides has been designed, based on the 1,3-dipolar cycloaddition of C-[(tert-butyldiphenylsilyl)oxy]methyl-N-methyl nitrone with ethyl 2-acetyloxyacrylate, followed by nucleosidation. The process has been successfully applied to all pyrimidine and purine nucleobases.
