[reaction: see text] A new solublepolymersupportsynthesis of nucleosides is described. The photochemical ring expansion of cyclobutanones in the presence of poly(ethylene glycol) (PEG) results in polymer-supported ribosides. These photoadducts can be cleaved from the polymer under Vorbruggen coupling conditions with TMS-protected purines and pyrimidines to give ribonucleosides. The method has been
