The invention relates to a preparation method of a lactam compound, and belongs to the field of medicinal chemistry. The preparation method comprises the following steps: carrying out an asymmetric hydrogenation reaction on raw materials under the action of a ruthenium catalyst and a hydrogen donor reagent, and carrying out a post treatment to obtain the target compound. The product obtained by the method is high in ee value, the method is simple and convenient, and the target compound can be easily, conveniently and efficiently obtained.

Alkenes (1) and 2,3-pyrrolidinediones (2) were treated with manganese(III) acetate in acetic acid at 23°C under a stream of dry air giving 1-hydroxy-8-aza-2,3-dioxabicyclo[4.3.0]nonan-9-ones (3) in good yields. The reaction at elevated temperature gave 4-ethenyl-2,3-pyrrolidinediones (6) and/or 4-alkyl-2,3-pyrrolidinediones (7) in good yields. A wide variety of 2,3-pyrrolidinediones having an alkoxycarbonyl, cyano, or acyl group at the 4-position were tested to delineate the scope and limitations of these reactions. The mechanisms for the formation of the products were also discussed.
