The [4 2] cycloaddition of cyclopentadiene to the (2R )-bornane-10,2-sultam derivative (À)-1b of fumaric monomethyl ester proceeds with high endo and p-facial diastereoselectivity in the presence of 0.5 mol-equiv. of TiCl 4 . The major diastereoisomer endo-(2R,3R )-2b, isolated in 87% yield by cryst
