  Enzyme-catalyzed hydrolyses of E/Z-diastereotopic and E/Z-diastereomeric esters. Effect on selectivity by reaction media

  摘要：

  PLE-catalyzed hydrolyses of different types of E/Z-diastereotopic diesters and E/Z-diastereomeric monoesters have been studied. Arylidenepropanedioic diesters are specifically hydrolyzed to the Z-half esters, whereas the de values for dialkylated methylene propanedioic diesters range between 33 and 79% (Z). D values for the hydrolyses of the 3-methyleneazetidin-2-ones in detergent-buffer systems depend on the size of the substituent in the alpha-position. Diastereoselectivity of these substrates is affected by addition of the cosolvents acetonitrile and methanol.
