The present invention has its objects to provide a method for reducing α-aminoketone derivatives under mild conditions with high stereoselectivity.
This invention is a method for reducing α-aminoketone which comprises reacting an α-aminoketone derivative of general formula (1) with a compound prepared from an organoaluminum compound of general formula (4), a sulfonic acid derivative of general formula (5), and an alcohol compound of general formula (6) to give an α-aminoalcohol derivative of general formula (7).
