  Biocatalytic preparation of optically active 4-(N,N-dimethylamino)pyridines for application in chemical asymmetric catalysis

  摘要：

  4-Chloro-2-(1-hydroxybenzyl)pyridine and 4-chloro-2-(1-hydroxyalkyl)pyridines were obtained with moderate to excellent enantiomeric excesses and high isolated yields by bioreduction with Baker's yeast of the corresponding ketones. The resulting optically active alcohols were transformed into adequate DMAP derivatives, which have been applied in asymmetric catalytic processes as nucleophilic catalysts in the stereoselective chemical alkoxycarbonylation of 1-phenylethanol or as chiral ligands in the enantioselective addition of diethylzinc to benzaldehyde.

  Chemoenzymatic synthesis of chiral 4-(N,N-dimethylamino)pyridine derivatives

  摘要：

  Chiral 4-(N,N-dimethylamino)pyridine derivatives have been prepared through a chemoenzymatic synthesis where the enzymatic kinetic resolution of a family of 4-chloro-2-(1-hydroxyalkyl)pyridines is the key step for the formation of potentially important chiral catalysts. Pseudomonas cepacia lipase (PSL) showed excellent enantioselectivity in the acylation of the (R)-enantiomers (E > 200) using vinyl acetate as acylating agent and THF as solvent, obtaining products and substrates enantiomerically pure and with excellent yields.
