    摘要: Disclosed is a process for producing novel optically active titanium alkoxide complexes which are excellent in catalytic activity and enantio-selectivity in carbon-carbon bond forming reactions (for example, Ene reaction, hetero-Diels-Alder reaction, Aldol reaction) and have high stability. The present process comprises reacting (R),(S),(RS)-catalysts or mixtures thereof selected from among optically active or racemic titanium alkoxide complexes represented by the following general formula (1), etc.: ##STR1## wherein R.sup.1 represents a methyl, lower alkoxy or trihalogeno group; R.sup.2 represents a hydrogen or halogen atom; R.sup.3 represents a hydrogen atom or a methyl group; and R.sup.4 represents a lower alkyl group, or R.sup.1 and R.sup.2 may form together a cyclo ring;with chiral activators [(R),(S),(RS)-diols or mixtures thereof, but excluding reactions between a racemic modification and another racemic modification] to thereby activate exclusively one of the enantiomers.

    摘要: 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.

    摘要: Disclosed is a method of producing an optically active fluorinated oxetane, which can be an important pharmaceutical or agricultural intermediate, by reaction of a fluorinated α-keto ester with an acyl alkenyl ether in the presence of a transition metal complex with an optically active ligand. This method utilizes a catalytic asymmetric synthesis process and does not require a stoichiometric amount of chiral source. It is thus possible to dramatically reduce the amount of use of the asymmetric catalyst especially when the reaction is performed at a high concentration of substrate (with the use of a small amount of reaction solvent) or in the absence of a reaction solvent (under neat conditions). Further, the target optically active fluorinated oxetane can be obtained with high yield and with very high optical purity. The product contains almost no difficult-to-separate impurity and shows high chemical purity.
