Abstract
![]() A three-component radical process is reported that, by coupling alkyl chlorides, maleimides, and heteroaromatic fragments, installs multiple biologically relevant heterocycles within complex cascade products. This method, which generates radicals via an SN2-based photochemical catalytic mechanism, activates substrates incompatible with or inert to classical radical-generating strategies.
We report a photoinduced three-component radical process, which couples readily available alkyl chlorides, maleimides, and heteroaromatic fragments to rapidly generate complex chiral products with high diastereocontrol. This method generates radicals via an SN2-based photochemical catalytic mechanism, which is not reliant on the redox properties of the precursors. It therefore grants access to open-shell intermediates from substrates that would be incompatible with or inert to classical radical-generating strategies. The redox-neutral conditions of this process make it tolerant of redox-sensitive substrates and allow the installation of multiple biologically relevant heterocycles within the cascade products.

Direct synthesis of aryl-annulated [ c]carbazoles by gold(i)-catalysed cascade reaction of azide-diynes and arenes. Chem Sci 2018; 9:8416-8425. [PMID: 30542591 PMCID: PMC6244455 DOI: 10.1039/c8sc03525c] [Citation(s) in RCA: 38] [Impact Index Per Article: 6.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/08/2018] [Accepted: 09/08/2018] [Indexed: 01/01/2023] Open
Abstract
The gold-catalysed annulation of conjugated alkynes bearing an azido group with arenes gave annulated [c]carbazoles. Using benzene, pyrrole, and indole derivatives as the nucleophiles, benzo[c]-, pyrrolo[2,3-c]-, and indolo[2,3-c]carbazoles were produced, respectively. The reaction proceeded through pyrrole and benzene ring construction accompanied by the formation of two carbon-carbon and one carbon-nitrogen bond and the cleavage of two aromatic C-H bonds. The mechanism of the reaction with pyrrole was investigated by density functional theory calculations. N,N'-dimethylated indolo[2,3-c]carbazole showed dual ultraviolet-visible-near-infrared and fluorescence spectral changes upon electrolysis.
