  Lipase-catalyzed enantioseparation of alcohols containing a tetrazole ring

  摘要：

  A simple chemoenzymatic method for the preparation of optically active (5-aryltetrazolyl-2)-4-butan-2-ol, (5-aryltetrazolyl-2)-propan-2-ol, and their acetates has been developed. The starting compounds (5-aryltetrazolyl-2)-4-butan-2-one and (5-aryltetrazolyl-2)-propan-2-one were obtained by a Michael-type addition of 5-aryl substituted tetrazoles to methyl vinyl ketone, and alkylation of 5-aryl substituted tetrazoles with chloroacetone, respectively. Their reduction with sodium borohydride afforded racemic mixtures of (5-aryltetrazolyl-2)-4-butan-2-oles and (5-aryltetrazolyl-2)-propan-2-oles. (C) 2012 Elsevier Ltd. All rights reserved.
