| titleOfInvention | Method for preparing optically active 5-hydroxy-3- (4'-hydroxyphenyl)-1, 1,3-trimethylindane |
| abstract | A process for resolving racemic diesters of (R,S)(±)-5-hydroxy-3-(4'-hydroxyphenyl)-1,1,3-trimethylindane is disclosed. The process utilizes a microbial enzyme derived from Chromobacterium viscosum to catalyze the enantioselective and regioselective hydrolysis of the (S)(-)-enantiomer of the racemic mixture to its corresponding monoester at a faster rate than the (R)(+)-enantiomer. A substantially pure (S)(-)-indane monoester is thereby formed, while the (R)(+)-indane diester remains unreacted. The (S)(+)-monoester and the (R)(+)-diester can then be hydrolyzed using conventional techniques to form optically active (R)(+)- and (S)(-)-5-hydroxy-3-(4'-hydroxyphenyl)-1,1,3- trimethylindane enantiomers for use as monomers in the synthesis of chiral polymers. |
