Microwave-assisted synthesis of 2'-O-aryluridine derivatives.

A new method for the synthesis of 2'-O-aryluridines was developed via the microwave-mediated reaction of 2,2'-anhydrouridine with aromatic alcohols. Aminophenol and aminonaphthol derivatives underwent selective 2'-O-arylation with 2,2'-anhydrouridine to produce 2'-O-(aminoaryl)uridine derivatives. These reactions proved to proceed without the need for any bases or solvents, but better results were obtained by use of N,N-dimethylacetamide (DMA) as the solvent in some cases.
