direct asymmetric reductive amination of a variety of ketone substrates, including 2-acetyl-6-substituted pyridines, β-keto esters, β-keto amides, and 1-(6-methylpyridin-2-yl)propan-2-one, has been disclosed for the first time (94.6% to >99.9% ee). With ammonium trifluoroacetate as the nitrogen source, various chiral corresponding primary amines were prepared in excellent enantioselectivity and conversion
