A direct alkoxycarbonylation/cyclization reaction is accomplished under visible light-induced photoredox catalysis. With this approach, a variety of ester-substituted indolo[2,1-a]isoquinolines are prepared in good to excellent yields. It worth noting that method not only can afford the synthesis but also provide an alternative route for generating complex target structures bearing carboxylic esters.

Photoredox catalysis (PRC) is a cutting-edge frontier for single electron-transfer (SET) reactions, enabling the generation of reactive intermediates both oxidative and reductive processes via photon activation catalyst. Although this represents significant step towards chemoselective and, more generally, sustainable chemistry, its efficacy limited by energy visible light photons. Nowadays, excellent alternative conditions are available to overcome these limitations, harvesting two different but correlated concepts: use multi-photon such as consecutive photoinduced electron transfer (conPET) combination photo- electrochemistry in synthetic photoelectrochemistry (PEC). Herein, we review most recent contributions fields activations organic functional groups. New opportunities chemists captured, selective reactions employing super-oxidants super-reductants engage unactivated chemical feedstocks, scalability up gram scales continuous flow. This provides comparisons between techniques (multi-photon photoredox PEC) help reader fully understand their similarities, differences potential applications therefore choose which method appropriate given reaction, scale purpose project.

The development of catalytic carbonylation reactions has increased considerably. Although many reviews/chapters/books on have been published, summaries cheap metal-catalyzed aryl halides and other chemical bonds with high dissociation energy C-Y (Y = O, N, H) are still very rare. Focusing green sustainable chemistry, this review summarizes discusses the achievements carbonylative transformations (C(sp2)-X) strong based non-expensive metal catalysts (Co, Mn, Mo, Ni, Fe, Cu), photochemical electrochemical systems developed in recent decades.

The photocatalyzed radical-triggered thio/selenosulfonylation–bicyclization of indole-tethered 1,6-enynes has been established for the first time, enabling synthesis various previously unreported thio/selenosulfonylated benzo[c]pyrrolo[1,2,3-lm]carbazoles with moderate to good yields under mild conditions. reaction pathway was proposed, consisting energy transfer, homolytic cleavage, radical addition, 5-exo-dig, coupling, and a Mallory cascade. This approach exhibits wide substrate compatibility excellent tolerability toward functional groups is characterized by its remarkable efficiency in both bond formation annulation.

Abstract In modern organic chemistry, harnessing the power of multicomponent radical reactions presents both significant challenges and extraordinary potential. This article delves into this scientific frontier by addressing critical issue controlling selectivity in such complex processes. We introduce a novel approach that revolves around reversible addition thiyl radicals to multiple bonds, reshaping landscape reactions. The key lies intricate interplay between reversibility energy landscapes governing C−C bond formation thiol‐yne‐ene developed not only allows prioritize cascade, dominating over alternative reactions, but also extends scope coupling products obtained from alkenes alkynes various structures electron density distributions, regardless their relative polarity difference, opening doors more versatile synthetic possibilities. present study, we provide powerful tool for atom‐economical C−S formation, paving way efficient synthesis molecules. Carrying out our experimental computational studies, elucidated fundamental mechanisms underlying cascades, knowledge can be broadly applied field chemistry.

A Mn(III)-mediated radical cascade cyclization of N-propargyl enamides with sodium sulfinates was developed. Mechanistic studies indicated that this process is mainly composed the chemoselective addition sulfonyl to C≡C bond and regioselective intramolecular 6-endo-trig cyclization. This protocol provided a powerful method for divergent synthesis diverse polysubstituted meta-sulfonylpyridines or 1,2-dihydropyridines just by varying solvent temperature featuring good functional group compatibility simple operation.
