Condensation of β-(4-methoxyphenyl)glutaconic anhydride (I) with phenetole under Friedel-Crafts conditions furnishes δ-(4-ethoxyphenyl)-δ-hydroxy-β-(4-methoxyphenyl)-α,γ-pentadienoic acid δ-lactone (IIa) and γ-(4-ethoxybenzoyl)-β-(4-methoxyphenyl)crotonic acid (IIIa).A similar condensation of I with diphenyl ether results in the formation of δ-hydroxy-β-(4-methoxyphenyl)-δ-(4-phenoxyphenyl)-α,γ-pentadienoic acid δ-lactone (IIb) and β-(4-methoxyphenyl)-γ-(4-phenoxybenzoyl)crotonic acid (IIIb).Some reactions of II and III have been studied.
