Photoredox-transition metal dual catalysis provides a unique platform for constructing sp 3 -rich chemical matter. Here, we report a nickel-catalyzed cross-coupling of commercially available or easily prepared redox-active NHP azetidine-2carboxylates with commercially available heteroaryl iodides to yield 2-heteroaryl azetidines. This "off-the-shelf" approach yielded products amenable to diversification giving access to novel saturated heterocyclic scaffolds useful for medicinal chemistry programs. An alternative mechanism for Hantzsch ester within nickel-catalyzed cross-coupling of heteroaryl halides and α-amino radicals is also presented.
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.
