An iodine-induced sulfonylation of quinoline-2-thiones with sodium arenesulfinates as sulfur sources for the synthesis of 4-aryl-2-(arylsulfonyl)quinoline derivatives is described. The 4-aryl-2-(arylsulfonyl)quinoline derivatives can be obtained in a moderate to good yields. This C-S bond cleavage and C-S cross-coupling proceeds in the absence of a metal under inexpensive and nontoxic conditions and it displays a broad substrate scope.

A metal-free, peroxide-free, and efficient procedure for the highly selective synthesis of quinolines and methylquinolines was reported. The main feature of this method was that the same substrate can produce quinolines and methylquinolines, respectively, under different reaction conditions. PEG-400 was used as both a reactant and solvent in this reaction. The utility of the designed procedure was also demonstrated by the derivatization of the products to bioactive compounds.

Catalyst-free and selective trifluoromethylative cyclization of acryloanilides using PhICF3Cl

Trifluoromethylation-triggered cyclization of alkenes provides a useful route to CF3-containing cyclic compounds. Current approaches to generate CF3-based initiators from a CF3 source require a catalyst or an activator. This work describes a catalyst-free protocol to innately produce electrophilic CF3 species from PhICF3Cl for trifluoromethylative cyclization of acryloanilides. A new domino biscyclization of dienes has been developed leading to trifluoroethylated tetrahydroindenoquinolinones with chemo- and stereo-selectivity.
