NOVEL BETA-DIKETONE COMPOUNDS, BETA-DIKETONE COMPOUNDS COORDINATED TO METAL, METHOD OF ORGANIC SYNTHESIS WITH THESE, AND CATALYST

摘要

The present invention provides a novel β-diketone compound represented by formula (3): [wherein X represents (CH₂)_n; n represents an integer of 2-20; and the CH₂ of X may be replaced by an oxygen atom, a hetero ring, or an aromatic ring, but oxygen atoms are not sequentially arranged in X], and a metal-coordinated β-diketone compound in which a metal is coordinated with the β-diketone compound. The compound of the present invention can be easily synthesized, and serves as a catalyst for asymmetric synthesis which can provide high asymmetric yield and chemical yield.
