## Abstract Coenzyme F430 pentamethyl ester **2** was partially hydrolyzed to a mixture of the five F430 tetramethyl esters **7**–**11**, which were separated by HPLC and identified by means of a full NMR characterization. The tetramethyl ester with a free COOH group at the side chain at C(3) of F4
