Dominos! The multivalent reactivity profile of tertiary skipped diynes has been conveniently exploited in the domino and diversity‐oriented synthesis of fully substituted pyrazoles and 1,4‐diazepane derivatives (see scheme). The developed manifold is chemically efficient and simple to operate. In addition, the resulting N‐containing heterocycles are obtained in a regio‐ and chemoselective manner.
