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).
本发明的目的是提供一种在温和条件下以高立体选择性还原α-氨基酮衍生物的方法。
本发明是一种还原α-氨基酮的方法,它包括将通式(1)的α-氨基酮衍生物与由通式(4)的有机铝化合物、通式(5)的磺酸衍生物和通式(6)的醇化合物制备的化合物反应,得到通式(7)的α-氨基醇衍生物。
