Abstract

Several furan compounds bearing conjugated trans C=C plus carbonyl moieties appended at the C2 position of the heterocycle were synthesized and characterized. Near-UV irradiation in bulk and in concentrated solutions induced their dimerization through a [pi 2 + pi 2] cycloaddition reaction between an excited and a ground state molecule. In dilute solutions, the excited species underwent predominantly trans-cis isomerization to give the equilibrium mixture of the isomers. (c) 2005 Elsevier B.V. All rights reserved.
