Abstract
A biocatalytic method for the synthesis of 2-(N,N-dimethyl amino)ethanol and/or choline esters of acrylic acid and/or methacrylic acid comprising reacting 2-(N,N-dimethylamino)ethanol and/or choline with acrylyl-CoA and/or methacrylyl-coA in the presence of a biocatalyst with choline acetyltransferase activity. The acrylyl-CoA and/or the methacrylyl CoA is formed by the reaction of acrylate and/or methacrylate with coenzyme A in the presence of ATP and a biocatalyst with S-acetyl coenzyme A synthetase activity.
