Abstract: The present invention discloses a method for directly constructing highly optically active tetrasubstituted allenic acid compounds, i.e., a one-step process for directly constructing highly optically active axially chiral tetrasubstituted allenic acid compounds by using tertiary propargyl alcohol, carbon monoxide and water as reactants in an organic solvent in the presence of palladium catalyst, chiral diphosphine ligand, monophosphine ligand and organic phosphoric acid. The method of the present invention has the following advantages: operations are simple, raw materials and reagents are readily available, the reaction conditions are mild, the substrate has high universality, the functional group has good compatibility, and the reaction has high enantioselectivity (90%˜>99% ee).
