Rhodium(III)-catalyzed olefinic C--H alkynylation of enamides at room temperature.

Rh(III)-catalyzed C--H olefinic alkynylation of enamides for the stereospecific construction of synthetically useful Z-type enynamides is reported. This protocol displays good functionality tolerance and operational simplicity thus providing an alternative synthetic opportunity for the ease of access to specific 1,3-enyne derivatives.
