The information in the text is summarized as follows:
An asym. intermol., three-component radical-initiated dicarbofunctionalization of 1,1-diarylalkenes with diverse carbon-centered radical precursors and electron-rich heteroaromatics by a copper(I) and chiral phosphoric acid cooperative catalysis strategy has been developed, providing straightforward access to chiral triarylmethanes bearing quaternary all-carbon stereocenters with high efficiency as well as excellent chemo- and enantioselectivity. The key to success is not only the introduction of a sterically demanding chiral phosphoric acid to favor radical difunctionalization over the otherwise remarkable side reactions but also the in situ generation of carbocation intermediates from benzylic radical to realize asym. induction with the aid of a removable hydroxy directing group via cooperative interactions with chiral phosphate. D. functional theory calculations elucidated the critical chiral environment created by the hydrogen-bonding and ion-pair interactions between the chiral phosphoric acid catalyst and substrates, which leads to the enantioselective C-C bond formation. The experimental process involved the reaction of 5-Fluoro-1H-indole(cas: 399-52-0SDS of cas: 399-52-0)
5-Fluoro-1H-indole(cas: 399-52-0) is a member of aromaticfluorinated building blocks. Fluorine-containing aromatics have been incorporated into crop-protection chemicals (herbicides, insecticides, fungicides). Liquid crystals, positron emission tomography, and imaging systems represent new areas where fluoroaromatics and fluoroheterocyclics have gained attention.SDS of cas: 399-52-0
