Kitazume, Tomoya,Lin, Jenq Tain,Yamazaki, Takashi
, p. 235 - 238 (1991)
Stereoisomers of unnatural 4,4,4-trifluorothreonine are obtained through enzymatic resolution, and the absolute configuration of these materials is determined. 4,4,4-Trifluorothreonine thus prepared was evaluated for antifugal or antitumor activity.
Stereoselective Preparation of Ethyl 2,3-Dihydroxy-4,4,4-trifluorobutyrates via Enzymatic Optical Resolution
Yamazaki, Takashi,Okamura, Naoko,Kitazume, Tomoya
, p. 521 - 524 (1990)
Ethyl 2,3-dihydroxy-4,4,4-trifluorobutyrate was prepared in a highly diastereo- as well as enantioselective manner via enzymatic optical resolution followed by chemical transformations with complete retention of their configurations.

Paragraph 0088; 0095, (2017/09/26)
The purpose of the present invention is to provide a fluorine-containing alpha,beta-unsaturated aldehyde, a method for producing same, an optically active fluorine-containing compound using the fluorine-containing alpha,beta-unsaturated aldehyde, and a method for producing same. This method for producing a fluorine-containing alpha,beta-unsaturated aldehyde is a method for producing a fluorine-containing alpha,beta-unsaturated aldehyde represented by formula (1) and comprises: an oxidizing step of oxidizing an alcohol represented by formula (2) in a high-boiling-point solvent, which has a higher boiling point than the corresponding alpha,beta-unsaturated aldehyde, by using an oxidizing agent that is insoluble to the high-boiling-point solvent; and a purifying step of purifying the reaction solution obtained in the oxidizing step by distillation. In formulae (1) and (2), R1 and R2 each independently represent a hydrogen atom or a fluorine atom, and X is 2 or 3.
Practical synthesis of 4,4,4-trifluorocrotonaldehyde: A versatile precursor for the enantioselective formation of trifluoromethylated stereogenic centers via organocatalytic 1,4-additions
