Several privileged starting materials that allow access to a variety of different heterocyclic scaffolds through judicious choice of reaction conditions (and coupling partner) have emerged. This microreview focuses on the development and use of four of these starting material types in cascade reactions involving the palladium‐ or copper‐catalysed formation of aromatic carbon–nitrogen, carbon–oxygen or carbon–sulfur bonds.
Eine zu wenig beachtete Klasse aromatischer Heterocyclen, die Cinnoline, wird durch die Kombination aus einem leicht verfügbaren Kupferkatalysator, einem einfach aufgebauten Hydrazidnucleophil und bekannten difunktionalisierten Bausteinen in einem neuen und flexiblen Verfahren zugänglich (siehe Schema).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
