N,N-Dialkyl-3,3,3-trifluoropropanamides were readily synthesized in good to excellent yields through N,N-dialkyl(3,3,3-trifluoro-1-propynyl)amines, which were generated by the reaction of N,N-dialkyl(2,2,3,3,3-pentafluoropropyl)-or -(2,3,3,3-tetrafluoro-1

N,N-Dialkyl(3,3,3-trifluoro-1-propynyl)amines were prepared by a three-step procedure starting from commercially available 2,2,3,3,3-pentafluoropropanol. The reactions of these trifluoromethylated ynamines with some electrophiles, such as aldehydes, halog
A convenient preparation of 3,3,3-trifluoro-1-propynylamines and their Lewis acid catalyzed reaction with carbonyl compounds leading to (Z)-α-(trifluoromethyl)-α,β-unsaturated amides

N,N-Dialkyl(3,3,3-trifluoro-1-propynyl)amines were readily prepared by a three-step procedure starting from commercially available 2,2,3,3,3-pentafluoropropanol. These fluorinated alkynylamines reacted smoothly with a variety of aldehydes or ketones in the presence of a catalytic amount of Lewis acid and molecular sieves 4A at ambient temperature to produce the corresponding α(trifluoromethyl)-α,β-unsaturated amides in good to excellent yields with high Z-stereoselectivity.
