Description and Uses

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 using NaBH4?or 2-picoline borane complex, affording the target trifluoroethylamino compounds in moderate to good yields. Another general application of trifluoroacetaldehyde is the synthesis of chiral α-substituted trifluoroethylamino compounds.
