Reductive amination of carbonyl compounds continues to be a fundamental strategy for the synthesis of structurally diverse amines, which are key intermediates in medicinal chemistry and the preparation of complex natural products. In this study, we present an efficient protocol for the reductive amination of aldehydes with aryl amines using a dual catalytic system based on Scandium(III) triflate [Sc(OTf)3] supported on acidic silica. The Lewis acid–mediated activation of the carbonyl group is coupled with Hantzsch-1,4-dihydropyridine (HEH) as a biomimetic organic hydride donor. Under optimized conditions in toluene at room temperature, a wide range of secondary amines were obtained with excellent chemoselectivity and high isolated yields. The protocol proceeds under mild conditions, avoids harsh reagents, and exhibits broad functional-group tolerance, highlighting its potential as a practical and environmentally benign approach for amine synthesis.
