Preparation des acides alkyl et arylalkyl-5 methyl-2 benzofurannedicarboxyliques-6,7. Application a la synthese de derives de nouveaux heterocycles

Direct formation of 5-alkyl or arylalkyl 2-methylbenzofuran 6,7-dicarboxylic acid derivatives from Diels-Alder adducts of 5-alkyl or arylalkyl 2-acetonylfurans and dimethyl acetylenedicarboxylate is promoted by boron trifluoride etherate in methylene chloride at room temperature.The structures of these new compounds were established from their 1H and 13C nmr spectra.In 1,1,2,2-tetrachloroethane and in the presence of aluminium chloride, 5-arylalkylbenzofuran anhydrides undergo an intramolecular Friedel-Crafts acylations leading to new polycyclic benzofuran derivatives.
