Abstract
Enantioenriched cyclic β-amino alcohols, trans-2-aminocyclohexanols (ee, >99%), trans-2-aminocyclopentanols (ee, >99%), trans-1-amino-2-indanols (ee, >99%) and trans-2-amino-1-indanols (ee, ∼98%) were prepared in high yields via an Arthrobacter sp. Lipase/PLAP catalyzed kinetic resolution of racemic phthalimido acetates. The addition of toluene as a co-solvent dramatically improved the hydrolysis and enantioselectivity, whereas for indanols, substrate immobilization on Celite improved the efficacy of the kinetic resolution.
