α,β-UNSATURATED KETONES IN SUBSTITUTIVE ADDITION WITH 2-ALKYLFURANS AND SOME TRANSFORMATIONS OF THE REACTION PRODUCTS

Article abstract of DOI:10.1007/BF00506982

The substitutive addition of cyclic α,β-unsaturated ketones with 2-alkylfurans proceeds in the presence of catalytic amounts of sulfuric acid to give the corresponding furyl ketones.The latter were converted by Kishner reduction to cycloalkylfurans and were also converted to ethyleneketals, which form adducts with maleic anhydride.
