The synthesis of various trifluoromethylated amino compounds was studied using trifluoroacetaldehyde, an industrial bulk material, as a starting compound. One general application of trifluoroacetaldehyde is the preparation of trifluoroethylamino derivatives via reductive amination reaction. This synthesis includes the formation of the corresponding N,O-acetal intermediates followed by their reduction

The first organocatalyticasymmetric addition of thiols to trifluoromethylaldimine for the construction of chiral trifluoromethylated N,S-acetals has been achieved in high yields (up to 99%) and excellent enantioselectivities (up to 95% ee) with 1 mol% of a bifunctional organocatalyst.

This paper reports on the preparation of 4-(trifluoromethyl)azetidin-2-ones and their synthetic potential as eligible new building blocks for the construction of CF3-containing azetidines, diaminopropanes, aminopropanol derivatives, 1,3-oxazinanes, and 1,3-oxazinan-2-ones. This β-lactam building block approach provides a convenient new entry into trifluoromethylated scaffolds as useful synthetic intermediates
