dehydrogenative cycloisomerization of 1,4‐enyne esters in the presence of 2,3‐dichloro‐5,6‐dicyanobenzoquinone (DDQ) or N‐fluorobenzenesulfonimide (NFSI) is described. The synthetic versatility of the methodology was exemplified by a gram‐scale reaction of one example, the ease to realize subsequent functional transformations of an adduct, and the application of the method to the synthesis of the bioactive
