Trifluoropyruvamide in their hydrates forms participate in various Friedel-Crafts type reactions with electron rich aromatic compounds. Good diastereoisomeric excess have been obtained starting from the chiral isobornylamine derivative.

Trifluoropyruvamides in their hydrated form readily react with diazo esters affording new trifluoromethyl epoxides. Activating the pyruvamide with trifluoroacetic anhydride leads to a complete change in selectivity with the formation of a new diazo compound.
