Dicarboxylic acid monoesters

Dicarboxylic Acid Monoesters. Enzymatic synthesis of monoesters of dicarboxyUc acids by hydrolysis of the corresponding diesters is a widely used and thoroughly studied reaction. It is catalyzed by a number of esterases, Upases, and proteases and is usually carried out in an aqueous buffer, pH 6—8 at room temperature. Organic cosolvents may be added to increase solubiUty of the substrates. The pH is maintained at a constant level by the addition of aqueous hydroxide. After one equivalent of base is consumed the monoesters are isolated by conventional means. [Pg.332]

The mechanochemical technique has also been applied to the asymmetric opening of me o-anhydrides, catalyzed by the cinchona alkaloid quinidine (Scheme 8.4). A simple procedure affords the optically active dicarboxylic acid monoesters in high yields. Even mixtures of purely solid substrates react under these conditions, and no solvent is required, which significantly simplifies the product isolation step. ... [Pg.277]
