Significance

The present paper describes a three-component Kabachnik-Fields reaction catalyzed by a chiral scandium(III)-N,N′-dioxide complex. The α-amino phosphonates were obtained in good yields and with high enantioselectivity. While catalytic asymmetric Kabachnik-Fields reactions have been previously reported (X. Cheng et al. Angew. Chem. Int. Ed. 2008, 47, 5079), advantages of this procedure are the mild reaction conditions and that the reaction was performed on a 5 mmol scale without loss of reactivity or enantioselectivity.
