Concise and selective : The procedure‐controlled synthesis of the title compounds has been achieved for the first time by an organolithium‐promoted convergent tandem annulation involving readily available terminal alkynes, chalcogen elements (S, Se, and Te), carbodiimides, and acid chlorides. A novel 1,5‐acyl migration is considered to be essential for this useful transformation.
