Article abstract of DOI:10.1016/S0022-1139(00)82836-5

Intramolecular Diels-Alder reactions of furan derivatives each containing a trifluoromethyl group in the dienophilic part or the tethering chain of the dienophile to the furan ring showed a notable electronic effect of the trifluoromethyl group on the ste
