Abstract
A simple one-step route for the conversion of naphthols and phenols with tetrahydrofuran into corresponding 2-aryltetrahydrofurans using Amberlyst-15 as a catalyst is reported. This is the first example of the acid-mediated formation and rearrangement reactions of tetrahydrofuranyl ethers prepared from the tetrahydrofuran and aromatic/aliphatic hydroxy compounds.

General Procedure for Tetrahydrofuranylation of Aromatic and Aliphatic Hydroxy Compounds
THF, aromatic or aliphatic hydroxy compounds, and Amberlyst-15 was stirred for 5–8 h. At the end of the reaction, the mixture was filtered to remove the Amberlyst-15 resins. The organic layer was dried over Na2SO4, filtered, and the solvent was evaporated under reduced pressure, and the products were purified by chromatographic methods.
