The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: 5-Fluoroindoline( cas:2343-22-8 ) is researched.Recommanded Product: 2343-22-8.Yang, Guoqiang; Lindovska, Petra; Zhu, Dajian; Kim, Justin; Wang, Peng; Tang, Ri-Yuan; Movassaghi, Mohammad; Yu, Jin-Quan published the article 《Pd(II)-Catalyzed meta-C-H Olefination, Arylation, and Acetoxylation of Indolines Using a U-Shaped Template》 about this compound( cas:2343-22-8 ) in Journal of the American Chemical Society. Keywords: regioselective meta carbon hydrogen bond olefination indoline palladium catalyst; acetoxylation indoline palladium catalyst; arylation indoline palladium catalyst. Let’s learn more about this compound (cas:2343-22-8).
Meta-C-H olefination, arylation, and acetoxylation of indolines have been developed using nitrile-containing templates. The combination of a monoprotected amino acid ligand and the nitrile template attached at the indolinyl nitrogen via a sulfonamide linkage is crucial for the meta-selective C-H functionalization of electron-rich indolines that are otherwise highly reactive toward electrophilic palladation at the para-positions. A wide range of synthetically important and advanced indoline analogs are selectively functionalized at the meta-positions.
