- Convenient synthesis of α-trifluoromethyl amines via aminofluoroalkylation of arenes with N-trimethylsilyl α-trifluoroacetaldehyde hemiaminal
-
Aminofluoroalkylation of various heteroarenes or substituted benzenes with the N-trimethylsilyl hemiaminals, prepared from 1,1,1,3,3,3-hexamethyldisilazane and gaseous trifluoroacetaldehyde, smoothly underwent at room temperature in the presence of a Lewis acid. [(1-Aryl-2,2,2-trifluoro)ethyl]amines or bis[(1-aryl-2,2,2-trifluoro)ethyl]amines were afforded in moderate to high yields.

- An asymmetric synthesis of both enantiomers of 2,2,2-trifluoro-1-furan-2-yl-ethylamine and 3,3,3-trifluoroalanine from 2,2,2-trifluoro-1-furan-2-yl-ethanone
-
The selective conversion of 2,2,2-trifluoro-1-furan-2-yl-ethanone into (E)- and (Z)-oximes and oxime ethers and subsequent oxazaborolidine-catalyzed enantioselective reduction using different amino alcohols furnished both enantiomers of the important chir
