The use of water instead of benzene as the solvent can strongly influence the stereoselectivity and the rate of Diels-Alder reactions of 1,4-naphthoquinone derivatives with different dienes. Enantiomeric excess (e.e.) up to 38% is reached in the presence of a catalytic amount of bovine serum albumin.
