An efficient method for the asymmetric synthesis of β-trifluoromethylated β-amino ketonesvia addition of ketone-derivative enolates to trifluoromethylated sulfinylimine has been developed, with good chemical yields and excellent diastereoselectivities. This practical method was also proved to be suitable for large-scale preparation.
