β-Nitroacrylates and Phenols as Key Precursors of Arenofuran-3-carboxylates
Herein we report a new practical and efficient preparation of benzofuran and naphthofuran-3-carboxylates starting from β-nitroacrylates and phenols. The reaction is promoted by indium trichloride and leads the target compounds from good to very good yields under microwave irradiations.
