Abstract It has been established that on interaction of ethoxyacetaldehyde with acetyl-acetone, acetoacetic ester, and benzoylacetone in the presence of piperidine acetate, β,γ-unsaturated compounds are formed, viz., 3-(2-ethoxy)vinyl substituted acetylacetone, acetoacetic ester, and benzoylacetone. Methods are proposed for the synthesis of 2,3,5-trisubstituted 4,5-dihydrofurans in the presence of trifluoroacetic or acetic acids by the cylization of the linear condensation products.
