Nemoto, Tetsuhiro; Ishige, Yuta; Yoshida, Mariko; Kohno, Yuta; Kanematsu, Mutsumi; Hamada, Yasumasa published the artcile< Novel Method for Synthesizing Spiro[4.5]cyclohexadienones through a Pd-Catalyzed Intramolecular ipso-Friedel-Crafts Allylic Alkylation of Phenols>, Application In Synthesis of 152140-65-3, the main research area is stereoselective spirocyclohexadienone preparation intramol Friedel Crafts allylic alkylation; ipso Friedel Crafts intramol alkylation phenol reactant spirocyclohexadienone preparation; palladium catalyzed Friedel Crafts allylic alkylation spirocyclohexadienone preparation.
The first successful Pd-catalyzed intramol. ipso-Friedel-Crafts allylic alkylation of phenols, which provided a new access to spiro[4.5]cyclohexadienones, e.g. I, is described. The present method could be applied to catalytic enantioselective construction of an all-carbon quaternary spirocenter.
Organic Letters published new progress about Diastereoselective synthesis. 152140-65-3 belongs to class chiral-phosphine-ligands, and the molecular formula is C54H42N2O2P2, Application In Synthesis of 152140-65-3.
