Tertiary Skipped Diynes: A Pluripotent Building Block for the Modular and Diversity-Oriented Synthesis of Nitrogen Heterocycles
Dominos! The multivalent reactivity profile of tertiaryskippeddiynes 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.
