In situ mixed donor synthesis of ampicillin with ethylene glycol co-solvent

Biotechnol Bioeng. 2014 May;111(5):1054-8. doi: 10.1002/bit.25143. Epub 2013 Nov 20.

Abstract

Ethylene glycol has the ability to act as a reactant when employed as a co-solvent for the enzymatic synthesis of ampicillin from (R)-phenylglycine methyl ester and 6-aminopenicillanic acid. The side reaction positively affects yield because its product, (R)-phenylglycine hydroxyethyl ester, is an intermediate for ampicillin synthesis.

Keywords: ampicillin; co-solvent; transesterification; β-lactam antibiotics.
