Chiral N-phosphonyl imines attached by 1-naphthyl group were found to react with lithium malonate enolates smoothly to give chiral b-aminomalonates. Good yields and excellent diastereoselectivity were achieved for sixteen examples. The chiral auxiliary can be readily removed by treating with trifluo
