  • Publication number: 20030148481
    Abstract: The present intention relates to a method for kinetic resolution of racemates of alcohols with one or several stereogenic centers. The invention is particularly suitable for producing pharmaceutical agents or plant protective agents. According to the invention, first racemic alcohols are converted with fluorinated acylation agents into racemic fluorinated carboxylic acid esters. Subsequently, by lipase-catalyzed reaction of the racemic fluorinated carboxylic acid ester with alcohols the fluorous phase marking of the faster reacting enantiomer is canceled and that of the slower reacting enatiomer is maintained. Subsequently, the enantiomers are extractively separated by distribution between organic phase and fluorous phase.

  • Publication number: 20030003552
    Abstract: The invention relates to a method of kinetic resolution of racemates of alcohols or carboxylic acid esters. Fluorine phase marking of the quicker or more slowly reacting enantiomer is obtained by lipase-catalysed reaction of racemic alcohols with fluorinated carboxylic acid esters of racemic alcohols with water. The enantiomers are then extractively separated by division between an organic and a fluorine phase.
