A robust transition-metal-free one-step strategy for the synthesis of ynamides from sulfonamides and (Z)-1,2-dichloroalkenes or alkynyl chlorides is presented. This method is not only effective for internal ynamides but also amenable for terminal ynamides. Various functional groups, even the vinyl moiety, are compatible, and thus, this strategy offers the opportunity for further functionalization.
The present invention relates to compounds of the formula;

(Z)-beta-Trifluoromethyl enamines were prepared in high yield stereoselectively by reaction of 2-bromo-3,3,3-trifluoropropene with N-alkyl toluenesulfonamides and potassium t-butoxide in one pot via Michael addition and elimination processes. The (Z)-beta-trifluoromethyl enamines could be converted to the corresponding thermodynamically stable (E)-isomers promoted by Lewis acid catalysts at room temperature or thermal isomerization.
