Dicarboxylic esters: Useful tools for the biocatalyzed synthesis of hybrid compounds and polymers
Beilstein Journal of Organic Chemistry, 2015 Dicarboxylic acids and their derivatives (esters and anhydrides) have been used as acylating agents in lipase-catalyzed reactions in organic solvents. The synthetic outcomes have been dimeric or hybrid derivatives of bioactive natural compounds as well ...
