Abstract: We have reported the reactions of (E)-1-phenylsufonyl-3-alken-2-ones 1, as useful chelating dienophile, with cyclopentadiene catalyzed by a chiral titanium catalyst. The Diels-Alder adduct was prepared in 90% yield and 100% enantioselectivity1. Our continuing interest has been focused on utilization of the sulfonyl-functionalized bidentate chelating enone 1 as prochiral substrate in catalytic asymmetric reaction. This led us further investigate the expanding utilization of the substrate 1 in the asymmetric Diels-AIder reaction. Here the reaction of (E)-l-phealy-sufonyl-3-alken-2-ones 1 with open ring dienes was proceeded by the use of the chiral titanium catalyst.
