A silver-promoted three-component heterocyclization of alkynes, perfluoroalkyl halides, and 1,3-dinucleophiles was developed for the efficient synthesis privileged (E)-perfluoroalkenyl pyrroles. The reaction proceeded through a rationally designed sequence radical perfluoroalkylation intramolecular defluorinative [3 + 2]-heterocyclization. utility halide as perfluoroalkenyl reagent, by selective controllable functionalization two inert C(sp3)–F bonds at vicinal carbon centers on chain, provides new mode value-added organofluorides starting from easily available low-cost fluorinated feedstock.

A three-component reaction of trifluoromethyl enones, phosphine oxides, and alcohols in water solution is developed. This defluorinative occurs through a cascade process involving defluorophosphorylation, defluoroalkyloxylation, defluoroheteroannulation, enabling the modular synthesis furans with four distinct substituents: C2-alkyloxy, C3-trifluoromethyl, C4-phosphoryl, C5-(hetero)aryl groups. Moreover, apart from alcohol substrates, scope nucleophiles could be further extended to phenols, azacycles, or sulfonamide.

Transition-metal-catalyzed cycloadditions have been evolved as important and efficient methods to construct cyclic molecules.Among them, transition-metal-catalyzed using carbon monoxide (CO) gas the 1C synthon provide their unique powerful approaches build various molecules within a carbonyl group, which either acts an functional group cycloadducts, or can be further elaborated other groups.The tremendous advances in this field are introduced.

A straightforward preparation of diversified fluorinated indol-3-yl ketones was developed by the direct decarboxylative fluoroacylation indole carboxylic acids. The reaction could be performed on a gram scale under net conditions. Neither metal catalyst nor an additive employed. This methodology featured simple conditions, high efficiency, exclusive selectivity, broad substrate scope, and easy operation, which allowed it to meet green chemistry requirement modern pharmaceutical industry. Control experiments confirmed that radical process might involved in tandem sequence.

Abstract A method for the synthesis of symmetrical and unsymmetrical 3,3′‐bis(indolyl)methanes (3,3′‐BIMs) has been developed through direct heteroarylation indolyl‐containing di(hetero)aryl phosphonium salts with indole derivatives in aqueous media. This metal‐free reaction proceeds smoothly under mild conditions, eliminating need hazardous solvents expensive additives/catalysts typically used conventional routes, thereby highlighting synthetic practicality efficiency process. The success this approach is largely attributed to role water as a promoter, facilitating C−P bond functionalization salts. Furthermore, demonstrates broad substrate scope, good functional group tolerance, excellent scalability. Moreover, protocol can also be extended triindolylmethane compound diarylmethylated indole.

Abstract Indole motifs are omnipresent in nature and can be found many natural products as well pharmaceuticals. It is for this reason synthetic transformations of indole have become a topic interest the organic medicinal chemist community decades. In review, we emphasized functionalization indoles via transition‐metal‐free approaches. This review touches on aspects different sub‐sections, which gives proposition tactics employed an overview road ahead.
