Hotta, H. published the artcileConvenient preparation of axially chiral 1,1′-binaphthyl-2-carboxylates via the palladium-catalyzed carbonylation of 1,1′-binaphthyl-2-yl triflates, Quality Control of 126613-06-7, the publication is Journal of Molecular Catalysis (1989), 54(2), L5-L7, database is CAplus.
Binaphthylcarboxylates (S)-I (R = H, R1 = CO2Me), (R)-I (R = OMe, R1 = CO2Me), and (R)-I (R = OSO2CF3, R1 = CO2Me) were prepared by reaction of the corresponding I (R1 = OSO2CF3) with CO in the presence of a Pd(OAc)2-1,3-bis(diphenylphosphino)ethane catalyst. Enantiomeric excesses of 100% were attained.
