Paragraph 0064; 0080; 0081; 0082, (2018/10/19)
The invention provides a method using amide ester to prepare a diamine derivative. The method is characterized in that ester groups in amide esters containing both amide and ester functional groups are substituted to prepare the diamine derivative, and one of the diamine groups of the diamine derivative is carboxylic acid amide reserved from the amide ester raw materials. The method is cheap in raw material, easy in raw material obtaining, low in catalyst use amount, simple in reaction conditions and high in product stereoselectivity.
