  PPL-catalyzed resolution of 1,2- and 1,3-diols in methyl propionate as solvent. An application of the tandem use of enzymes.

  摘要：

  The Porcine Pancreatic Lipase (PPL)-catalyzed transesterification of 1-phenyl-1,2-ethanediol 1, 2-phenyl-1,2-propanediol 2, 1,2-decanediol 3, 1,2-pentanediol 4, 1,2-butanediol 5, 1,2-propanediol 6 and 1,3-butanediol 7 in methyl propionate as solvent was evaluated. In all substrates, the primary hydroxy group is esterified exclusively. The enantioselectivity displayed in this PPL-catalyzed reaction is moderate. The enantiomeric excess of diol (-)-1 is enhanced by subjecting propionate (-)-8, with a moderate ee (obtained by a PPL-catalyzed esterification of racemic 1 in methyl propionate), to an enzyme-catalyzed hydrolysis (tandem principle).
