from one heterocyclic base to another, is catalyzed by nucleoside phosphorylases (NPs) and is being actively developed and applied for the synthesis of biologicallyimportantnucleosides. Here, we report an efficient one-step synthesis of 5-substitited pyrimidine ribonucleosides starting from 7-methylguanosine hydroiodide in the presence of nucleoside phosphorylases (NPs).

6‐aminopurine (deoxy)ribonucleosides. A library of nucleoside analogues was synthesized and then submitted to enzymatic phosphorolysis as well. This assay revealed that 1‐, 2‐, 6‐ and 7‐modified nucleosides are accepted as substrates, whereas 8‐substituted nucleosides are not. A few transglycosylation reactions were carried out using 7‐methylguanosine iodide (4) as a D‐ribose donor and 6‐substituted purines
