A Convergent Synthesis of Polysubstituted Aromatic Nitriles via Palladium-Catalyzed C−H Functionalization

Abstract: A palladium-catalyzed C-H functionalization reaction for the synthesis of highly substituted aromatic nitriles is reported. The modularity of the reaction is demonstrated by the broad range of aryl iodides which can be coupled with metal cyanides and alkyl halides or aryl bromides.

“…[154] Valuable recent applications of this powerful concept towards the direct arylation of (hetero)arenes were designed by Lautens et al [155] For example, polycyclic 2H-indazoles were obtained by a palladium-catalyzed annulation (Scheme 77), [156] and a direct arylation/cyanation sequence afforded substituted benzonitriles (Scheme 78). [157] An elegant reaction sequence based on a catalytic direct arylation involving palladium migration was realized by Larock and co-workers. Interestingly, these early reports already highlighted that, among a variety of bases, CsOPiv was optimal.…”

“…[155] Beispiele sind die Synthese von polycyclischen 2H-Indazolen durch eine palladiumkatalysierte Anellierung (Schema 77) [156] oder die direkte Arylierungs-/Cyanierungs-Sequenz zur Synthese von substituierten Benzonitrilen (Schema 78). [157] Einige elegante Reaktionsfolgen, die auf einer direkten Arylierung unter Palladium-Wanderung beruhen, wurden von Larock et al realisiert. Schon in diesen frühen Arbeiten erwies sich CsOPiv unter verschiedenen Basen als optimale Wahl.…”

“…[38] Beispielsweise kann die frühe Sequenz aus Alkylierung und Olefinierung durch das Abfangen des Arylpalladium-Intermediats über eine Cyanierung ersetzt werden (Schema 23). [39] Auch die Verwendung eines Alkylhalogenids, das eine Acetylengruppe enthält, führte zu einer beeindruckenden Synthese vierfach substituierter helicaler Alkene (Schema 24). [40] Interessanterweise gelang Carretero und Mitarbeitern auch eine analoge Form der "Kaskadenkatalyse" zur Arylierung, die ohne Verwendung von Norbornen auskommt (Schema 25).…”
