Abstract:
An optically active, fluorine-containing carbonyl-ene product is produced by reacting a fluorine-containing α-ketoester with an alkene in the presence of a transition metal complex having an optically active ligand. There are Mode 1 of conducting this reaction in the absence of reaction solvent, Mode 2 of conducting this reaction in a solvent that is low in relative dielectric constant, and Mode 3 of conducting this reaction in a halogenated hydrocarbon-series solvent. In each of these three modes, it is possible to produce the optically active, fluorine-containing carbonyl-ene product with low cost.
