Latest Patents

Among her latest patents is a process for the resolution of ethyl, specifically a method for preparing ethyl 4,4,4-trifluoro-3(R)-hydroxybutanoate. This innovative process involves selectively hydrolyzing the ester functional group of the (S) enantiomer of ethyl (±)-4,4,4-trifluoro-3-hydroxybutanoate using a lipase in an aqueous medium. The non-hydrolyzed (R) enantiomer is then extracted for further use in the preparation of 4,4,4-trifluoro-1,3(R)-butanediol. Another significant patent involves the enantiomeric separation of (RS)-1-(4-chlorophenyl)-2-chloroethanol. This process utilizes an enantioselective enzymatic hydrolysis of (±)-α-(4-chlorophenyl)chloroethyl acetate, employing various lipases to yield a mixture of unhydrolyzed R-(-)-α-(4-chlorophenyl)chloroethyl acetate and S-(+)-1-(4-chlorophenyl)-2-chloroethanol.
