Regio‐ and Stereoselective Synthesis of Ynenamides through Gold (I)‐Catalyzed Hydroalkynylation of Ynamides

Abstract: Transition metal catalysis is a useful tool for C−C bond‐forming reactions. Of special interest is the hydroalkynylation reaction of alkynes, which provides a simple method for the synthesis of enynes representing interesting structural motifs in organic chemistry. So far, there are only a few examples of gold (I)‐catalyzed hydroalkynylation reactions. Herein, we were able to show experimentally that the gold (I)‐catalyzed hydroalkynylation of ynamides leads regio‐ and stereoselectively to the corresponding ynenamides, a rather unknown type of molecule. A wide range of products could be generated with yields up to 90 % and, in contrast to many other gold‐catalyzed alkyne dimerization reactions, alkyl groups are tolerated. Quantum chemical calculations and NMR labelling experiments reveal a mechanism via dual gold catalysis.
