Photocatalytic Decarboxylative\nAlkylation of Cyclic\nImine–BF<sub>3</sub> Complexes: A Modular Route to Functionalized\nAzacycles

Alkyl radicals generated via an acridine photocatalyzed\ndecarboxylation\nreaction of feedstock carboxylic acids engage with a range of cyclic\nimine–BF<sub>3</sub> complexes to provide α-functionalized\nazacycles in an operationally simple process. A three-component variant\nof this transformation incorporating [1.1.1]propellane as an additional\nreaction partner enables the synthesis of valuable bicyclopentane\n(BCP)-containing azacycles. Reactions exhibit good functional group\ncompatibility, enabling late-stage modification of complex bioactive\nmolecules.
