Arthrobacter sp. lipase catalyzed kinetic resolution of BINOL: The effect of substrate immobilization

(S)-1,1′-Binaphthyl-2,2′-diol was prepared in high optical purity (∼98%) via Arthrobacter sp. lipase (MTCC No. 5125) catalyzed kinetic resolution. The immobilization of the substrate on a solid inert support significantly improved the enantioselectivity factor (E) by almost sixfolds, i.e. from ∼27 to >180. The effect of acyl substituents and co-solvents were also studied.
