Ethyl 6-(4-ethoxy-phen-yl)-4-(furan-2-yl)-2-oxocyclo-hex-3-ene-1-carboxyl- ate

Abstract

The title compound, C21H22O5, was prepared by NaOH-catalysed cyclo-condensation of 3-(4-ethoxy-phen-yl)-1-(furan-2-yl)prop-2-en-1-one with ethyl acetoacetate. In the crystal, C - H⋯O and C - H⋯π inter-actions link the mol-ecules. In the title mol-ecule, the furan and cyclo-hexene rings are almost parallel [6.77 (11)°] and the cyclo-hexene ring is approximately perpendicular to the benzene ring [84.79 (5)°].
