The simultaneous increases in the enantioselectivity and activity, also induced by the addition of either a small amount of water to aprotic solvents or an amine such as benzylamine, indicate that preferential acceleration of the selective reaction has occurred, thus strongly suggesting the importance of the product desorption step on the modified sites.
