Enantiomers of ring-substituted 2-amino-1-phenylethanols by Pseudomonas cepacia lipase
摘要:
The enantiomers of 2-amino-1-phenylethanols were obtained enantiomerically pure (ee > 95%) at 50% conversion by the Pseudomonas cepacia lipase-catalysed O-acylation of amino alcohols or O-deacylation of the corresponding N,O-diacylated compounds.

Lipase PS from Burkholderia cepacia was successfully immobilized on Kynol(TM) ACC 507-15 active carbon cloth with and without ionic liquids as SILE catalysts. Activity, enantioselectivity and reuse of the catalysts were evaluated in the acylation of 1-phenylethanol with vinyl acetate in toluene and in hexane over the temperature range 25-60 degrees C. The presence of [EMIM][NTf2] clearly stabilized the enzyme against inactivation and preserved enantioselectivity in reuse in a process which is affected by the nature of the IL, solvent and substrate structure.
