In the Baylis-Hillman type reaction of chiral non-racemic N-sulfinimines 1 with cyclopent-2-en-1-one, we found that in the presence of a catalytic amount of the Lewis base PhPMe2 (10 mol%), diastereoselective reaction could be achieved in toluene at room temperature to give the normal Baylis-Hillman adducts 2 in good yields and high diastercoselectivities.
