The endo/exo stereoselectivity of the Diels-Alder cycloaddition between cyclopentadiene and 3-crotonoyl-2-oxazolidinone catalysed by Et 2 AlCl is temperature-and solvent-dependent. Eyring plots of ln(endo/exo) versus 1/T show different inversion temperatures (T inv ) depending on the reaction solven
The usefulness of Diels-Alder (D-A) reaction in organic synthesis has been attributed to its high stemoselectivity based on endo cycloaddition. which is explained by the concept of secondary orbital overlap in the transition state.1 Exo-mode addition, however, can predominate in some cases,"5 partic
