Ohmura, Toshimichi published the artcileIridium-Catalyzed C(sp3)-H Addition of Methyl Ethers across Intramolecular Carbon-Carbon Double Bonds Giving 2,3-Dihydrobenzofurans, Recommanded Product: 2-Isopropylanisole, the publication is Advanced Synthesis & Catalysis (2019), 361(19), 4448-4453, database is CAplus.
Intramol. addition of an O-Me C(sp3)-H bond across a carbon-carbon double bond occurs in the iridium-catalyzed reaction of Me 2-(propen-2-yl)phenyl ethers 2-MeC(=CH2)-4-R-3-R1-2-R2C6HOMe (R = H, Me, Cl, t-Bu; R1 = H, Me, MeO, CF3; R2 = H, Me, Ph, t-Bu, Br; R1R2 = CH=CH-CH=CH). The Ir/(S)-DTBM-SEGPHOS catalyst promotes the reaction efficiently in toluene at 110-135 °C to afford 3,3-dimethyl-2,3-dihydrobenzofurans I. Enantioselective C(sp3)-H addition is achieved in the reaction of Me 2-(1-siloxyethenyl)phenyl ethers 2-TBSOC(=CH2)-4-R3-3-R4-2-R5C6HOMe (R3 = H, Cl, t-Bu; R4 = H, MeO; R5 = H, Me, MeO, t-Bu, Cl; R4R5 = CH=CH-CH=CH), affording enantioenriched 3-hydroxy-2,3-dihydrobenzofuran derivatives II with up to 96% ee.
