The Diels-Alder (DA) reaction between cyclopentadiene (1) and 3-acryloyl-1,3-oxazolidin-2one (2), to give the endo adduet 5 as the main product, has been found to occur enantiosectively in the presence of catalytic amounts of magnesium perchlorate (MP) and 2,2-bis{2-[(4R)-phenyl-, [(4R,5S)and [(4R,5
