  Lipase-mediated resolution of 3-hydroxy-4-trityloxybutanenitrile: synthesis of 2-amino alcohols, oxazolidinones and GABOB

  摘要：

  Lipase-mediated kinetic resolution of 3-hydroxy-4-trityloxybutanenitrile gave the (S)-alcohol and (R)-acetate in good yields and high enantioselectivities. The resolution using Pseudomonas cepacia lipase (Burkholderia cepacia) immobilized on modified ceramic particles (PS-C) in diisopropyl ether gave the best results. The use of base additives in this transesterification drastically reduces the reaction time without effecting the yields or enantioselectivities. Resolved 3-hydroxy-4-trityloxybutanenitrile has been utilized for the synthesis of enantiomerically pure 5-tosyloxymethyl-1,3-oxazolidine-2-one, which is an important intermediate for the preparation of beta-adrenergic blocking agents and oxazolidinone based antimicrobial agents. Enantiomerically pure (R)-3-hydroxy-4-trityloxybutanenitrile and (S)-5-tosyloxymethyl-1,3-oxazolidine-2-one have been utilized in the enantioconvergent synthesis of (R)-GABOB.
