Selenium-catalyzed regioselective cyclization of unsaturated carboxylic acids using hypervalent iodine oxidants.

Fateh V Singh1, Thomas Wirth.   

Abstract

A new and convenient selenium-catalyzed regioselective cyclization of γ,δ-unsaturated carboxylic acids to the corresponding 3,6-dihydro-2H-pyran-2-ones is described. The cyclization products have been obtained in good to excellent yields using diphenyl diselenide as a catalyst and [bis(trifluoroacetoxy)iodo]benzene as a stoichiometric oxidant.
