3-(5-Aryl-2-furyl)acrylic acids were obtained by the reaction of 5-arylfurfurals with malonic acid.They were arylated by diazonium salts with decarboxylation and the formation of 5-aryl-2-styrylfurans.The latter were also obtained by the interaction of furylacrolein with diazonium salts.This reaction also gave 3-(5-aryl-2-furyl)acroleins and the corresponding arylfurylacrylic acids, which were arylated again with the release of CO2 and the formation of 5-aryl-2-styrylfurans. 3-(5-Aryl-2-furyl)acroleins were also synthesized by the condensation of 5-arylfurfurals with acetaldehyde under phase-transfer conditions.The s-trans configuration of the furan ring and the exocyclic double bond were established in the obtained compounds by the PMR method.
