The asymmetric Diels-Alder reaction of chiral l-[2-(p-tolylsulfinyl)-indolyl enones was examined. The cycloaddition of cinnamyl and crotonyl α,β-unsaturated enones with cyclopentadiene in the presence of a lanthanoid triflate as a Lewisacid proceeds smoothly to give the corresponding endo cycloadducts with high diastereoselectivity.
