                                    A new strategy to construct acyclic nucleosides with diverse side chains was developed. With Ag(I) salts as catalysts, the hydrocarboxylation, hydroamination, and hydrocarbonation reactions proceeded well, affording acyclic nucleosides in good yields (41 examples, 60-98% yields). Meanwhile, these reactions exhibited high chemoselectivities and E-selectivities.
