Polymerization of Achiral Carboxylic Acid Derivatives

An enzymatic oligonKrization versus lactonization of various hydroxyesters has been reported [31]. When unsubstituted fi, S, and e-hydroxyadd methyl esters 3 are subjected to the action of Pordne pancreatic lipase in anhydrous 

Lipase-catalyzed polymerization between an achiral dicarboxylic add and a primary glycol in an aqueous-organic mixture was report i [32]. A polycondensation of achiral 10-hydroxy fecanoic add cataly d by lipase in benzene has also been daimed, however no convincing evidence was presented [33]. 

Enzymatic polycondensation of a dicarboxylic add and a diol has been reported using lipase from Candida cylindracea. Pseudomonas sp., and Porcine pancreas [34]. Competition between linear polye er and macrocyclk lactone formation was observed depending on tlx reaction temperature.
