Metalloradical Catalysis: General Approach for Controlling Reactivity and Selectivity of Homolytic Radical Reactions

Angewandte Chemie International Edition, Год журнала: 2024, Номер 63(20)

Опубликована: Март 13, 2024

Abstract Since Friedrich Wöhler's groundbreaking synthesis of urea in 1828, organic over the past two centuries has predominantly relied on exploration and utilization chemical reactions rooted two‐electron heterolytic ionic chemistry. While one‐electron homolytic radical chemistry is both rich fundamental reactivities attractive with practical advantages, synthetic application been long hampered by formidable challenges associated control reactivity selectivity high‐energy intermediates. To fully harness untapped potential for synthesis, there a pressing need to formulate radically different concepts broadly applicable strategies address these outstanding issues. In pursuit this objective, researchers have actively developing metalloradical catalysis (MRC) as comprehensive framework guide design general approaches controlling stereoselectivity reactions. Essentially, MRC exploits metal‐centered radicals present open‐shell metal complexes catalysts activation substrates generate metal‐entangled key intermediates govern reaction pathway stereochemical course subsequent catalytic processes. Different from conventional transition complexes, operates through utilizing stepwise mechanisms.

Ligand-Enabled “Two-in-One” Metallaphotocatalytic Cross Couplings

ACS Catalysis, Год журнала: 2025, Номер 15(3), С. 1635 - 1654

Опубликована: Янв. 15, 2025

Metallaphotoredox cross coupling (MCC) is ranking among the most advanced synthetic methodology as it can access chemical space that difficult to attain under conventional conditions. Earlier developed MCC mandates an independent transition metal catalyst and respective photocatalyst, thus constituting a dual catalytic manifold. Complementarily, paradigm-shifting metallaphotoredox strategy capitalizes on single photoreactive complex emerging, which brings not only operational simplification but also unexpected mechanistic insights. This perspective compiled recent advances in monocatalytic couplings categorized them based ligands confer distinct photoreactivities various mechanisms. To this end, ligand-enabled oxidative addition, transmetalation, reductive elimination other radical-involving pathways were summarized with notable examples. In way, we wish provide handy guideline for readers who are interested emerging field inspire more future endeavors MCCs beyond.

Remote Enantioselective [4 + 1] Annulation with Copper-Vinylvinylidene Intermediates

Journal of the American Chemical Society, Год журнала: 2022, Номер 144(46), С. 21347 - 21355

Опубликована: Ноя. 11, 2022

The first copper-catalyzed enantioselective [4 + 1] annulation of yne-allylic esters with 1,3-dicarbonyl compounds was realized through an elegant remote stereocontrol strategy. very ε regioselective nucleophilic substitution developed by employing a novel chiral copper-vinylvinylidene species from the new C4 synthon esters. Thus, greatly diverse spirocycles were obtained ample scope and excellent levels chemo-, regio-, enantioselectivities. Moreover, detailed mechanistic studies suggest Conia-ene cascade pathway on stereochemical induction progress.
