Abstract

This invention relates to novel compositions of matter which are esters with enhanced water solubility, for use in aqueous enzymatic resolution reactions of racemic mixtures of these esters for producing the separate chiral isomers of the racemic mixture. The invention also relates to novel methods for preparing these esters. The importance of the production of the separate chiral isomers of the racemic mixtures resides in the isolation of the isomers which frequently have different biological activities. Of particular significance regarding the water soluble esters of this invention is that they are derivatized with groups which enhance their aqueous solubility and their reactivity with enzymatic resolving methods which are mediated in an aqueous environment. In addition, the importance of these compounds resides in their being useful in novel methods for facilitating the enzymatic resolution reactions of racemic mixtures of esters, which are derivatized with groups which enhance the esters' aqueous solubility, in 1) a homogeneous aqueous reaction system where an extractive phase is not present, 2) a multiphase dispersion extractive reaction where an extractive phase is present, a…
