The present invention relates to the design and synthesis of a class of novel chiral phosphine ligand, 1,2-bis(diphenylphosphinoalkylamido)-1,2-disubstituted ethane, and use in asymmetric catalytic reactions, such as asymmetric catalytic synthesis of pyrazoline-5-one with a chiral quaternary carbon center, i.e., highly enantioselective synthesis of 3-methyl-4-benzyl-4-(2-butyl-2,3-butadienyl)pyrazoline-5-one by using 3-methyl-4-benzylpyrazoline-5-one and benzyl (2-butyl-2,3-butadienyl) carbonate with tris(dibenzylideneacetone)dipalladium-chloroform adduct and this novel ligand as catalysts. The ligand designed by this present invention has the following advantages: the structure is novel, the synthesis and enlarge are simple, the enantioselective control effect in the practical reaction is excellent, which has a broad application prospect in chiral catalysis.
