Dihydroquinazolinones as adaptative C(sp3) handles in arylations and alkylations via dual catalytic C–C bond-functionalization Lv, Xin-Yang Abrams, Roman Martin, Ruben C–C bond forming cross-couplings are convenient technologies for the construction of functional molecules. Consequently, there is continual interest in approaches that can render traditionally inert functionality as cross-coupling partners, included in this are ketones which are widely-available commodity chemicals and easy to install synthetic handles. Herein, we describe a dual catalytic strategy that utilizes dihydroquinazolinones derived from ketone congeners as adaptative one-electron handles for forging C(sp3) architectures via α C–C cleavage with aryl and alkyl bromides. Our approach is achieved by combining the flexibility and modularity of nickel catalysis with the propensity of photoredox events for generating open-shell reaction intermediates. This method is distinguished by its wide scope and broad application profile––including chemical diversification of advanced intermediates––, providing a catalytic technique complementary to existing C(sp3) cross-coupling reactions that operates within the C–C bond-functionalization arena. 2022-05-31T13:39:25Z 2024-04-23T10:56:51Z 2022-05-31T13:39:25Z 2024-04-23T10:56:51Z 2022-05-31T13:39:25Z 2024-04-23T10:56:51Z 2022-05-03 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion http://hdl.handle.net/2072/522348 https://doi.org/10.1038/s41467-022-29984-0 eng FEDER/MCI–AEI/PGC2018-096839-B-I00 MCIN/AEI/10.13039/ 501100011033 (CEX2019-000925-S) grant agreement No 883756 info:eu-repo/semantics/openAccess You have selected the Attribution-NonCommercial-NoDerivatives 4.0 International License.
