Irradiation of the chiral sensitizers 1,1'-bis(2,4-dicyanonaphthalene) and 1,1'-bis(2,10-dicyanoanthracene) catalyzes the triplex Diels-Alder reaction of trans-β-methylstyrene with 1,3-cyclohexadiene to form the [4+2] cycloadducts endo-trans-6-methyl-5-phenylbicyclo[2.2.2]oct-2-ene. When the sensitizer isoptically active and the irradiation in performed at low temperature in ether or toluene solution
