A Copper(I)-Catalyzed Enantioselective γ-Boryl Substitution of Trifluoromethyl-Substituted Alkenes: Synthesis of Enantioenriched γ,γ-gem-Difluoroallylboronates
Kojima, Ryoto,Akiyama, Sota,Ito, Hajime
, p. 7196 - 7199 (2018)
The first catalytic enantioselective γ-boryl substitution of CF3-substituted alkenes is reported. A series of CF3-substituted alkenes was treated with a diboron reagent in the presence of a copper(I)/Josiphos catalyst to afford the c
Systematic study of the reactivity of (E)-4,4,4-trifluorobut-2-en-1-yl 4-methylbenzenesulfonate towards different classes of nucleophiles

A systematic study of the reactivity of (E)-4,4,4-trifluorobut-2-en-1-yl 4-methylbenzenesulfonate towards different classes of nucleophiles (alcohols, amines, thiols and malonates) was performed. A single set of reaction conditions (with small variations) allowed the isolation of the substitution product in moderate to good yields for all the nucleophiles tested with the exception of benzyl alcohol and indole.

gem-Difluoroalkenes have steric and electronic profiles similar to those of ketones, aldehydes, and esters, and consequently have been used widely as carbonyl isosteres in modern drug discovery. Although many attempts have been made to achieve gem-difluor
4-SUBSTITUTED PYRR0LIDIN-2-0NES AND THEIR USE
-
Page/Page column 24, (2010/11/26)
The present invention relates to optically enriched or substantially optically pure 4-substituted-pyrrolidin-2-ones of formula (III), and their uses for the synthesis of 2-oxo-pyrrolidin-l-yl derivatives.

Kelly, Stephen M.,Skelton, Graham,Jones, Cliff,Minter, Vicki,Tuffin, Rachel
, p. 873 - 880 (2007/10/03)
We have synthesised a new class of compounds incorporating a trifluoromethyl group in the terminal alkoxy or alkenyloxy chain. Compounds containing several aromatic rings were synthesised with a view to producing compounds of high birefringence. This also
