An Umpolung Strategy for Palladium-Catalyzed Dearomative Allylation toward Eight-Membered N-Heterocycles
{{output}}
In this study, umpolung palladium catalysis was developed for achieving 1,2-dearomative allylation followed by intramolecular cyclization. The dearomatization involves activated N-arenes and the in situ generated nucleophilic η1-allyl-palladium species from a... ...
