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

Abstraci: The endolexo selecttviry of Diels-Alder reactions tn water and methanol is studied with semiempirical methods using the SCRF approach and a combined quantum chemical (transition state) and molecular mechanics (solvent molecules) method lQCIMA4) to determine the effect of protic solvents on
