Abstract The racemicmixtures of 1-aryloxy-3-nitrato-2-propanols and 1-aryloxy-3-azido-2-propanols were resolved with moderate selectivity by the lipase-mediated acylation with vinyl acetate. The effects of the nature, position, and spatial requirements of the phenyl-ring substituents on the resolution degree were investigated.
Kinetic resolution of racemic 1-azido-3-aryloxy-2-propanols la-g was performed using supported lipase of Candida antarctica-B (Novozym(R) SP 435) in toluene at 4 degrees C with isopropenyl acetate as the acyl donor to afford the optically active (S)-alcohols 2a-g and their corresponding (R)-acetates 3a-g with E values from 56 to 72, (C) 2000 Elsevier Science Ltd.
