Benzimidazolone and benzoxazolone moieties are important scaffolds in a variety of pharmaceutical molecules. These bicyclic heterocycles are usually prepared from a benzene derivative through the construction of an additional five‐membered heterocyclic ring. We report herein a method that enables the efficient synthesis of highly substituted benzimidazolone and benzoxazolone derivatives by building...
Strom liefert die Energie für die Synthese von hochsubstituierten Benzimidazolonen und Benzoxazolonen. Die Benzol‐ und heterocyclischen Ringe werden aus acyclischen Substraten aufgebaut, wie H.‐C. Xu und Mitarbeiter in ihrer Zuschrift auf S. 9115 beschreiben. An der Anode (
= Yang‐Pol) gibt das Substrat 4 Elektronen und 4 Protonen ab, um das benzokondensierte heterocyclische Produkt zu bilden. An...
