Thianthrenation is a useful strategy for the late-stage diversification of complex small molecules owing to positional selectivity and synthetic versatility thianthrenium salts as electrophilic linchpins. However, substrate-dependent identification suitable reaction conditions thianthrenation can be difficult. Reported functionalization vary significantly and, in some instances, lack robustness practicality. Herein, we report generalized approach preparation two manifolds practical, robust, parallel salts.

We report a Pd-catalyzed decarboxylative Negishi coupling reaction for efficient biaryl synthesis from various zinc aryl carboxylates, including polyfluorobenzoates and heteroaryl using DMF as the solvent. This mild exhibits broad substrate scope enables late-stage functionalization of bioactive molecules. Mechanistic studies show that DMF-assisted catalyzes decarboxylation polyfluorinated carboxylates to generate arylzinc reagents in situ, which then undergo catalyzed by palladium with arylthianthrenium salts form compounds. Notably, this protocol represents rare example zinc-mediated demonstrates novel strategy preparing easily accessible (hetero)aryl carboxylic acids.

Synthesis of Sulfoxides by Palladium-Catalyzed Arylation of Sulfenate Anions with Aryl Thianthrenium Salts

The Journal of Organic Chemistry, Год журнала: 2024, Номер 89(18), С. 13319 - 13328

Опубликована: Сен. 3, 2024

A novel and highly efficient Pd-catalyzed arylation of sulfenate anions with aryl thianthrenium salts is demonstrated. This procedure provides a practical protocol to synthesize various diaryl alkyl sulfoxides in moderate-to-good yields. The new approach shows mild reaction conditions, broad substrate scope, good functional group tolerance.
