Initially, cloprostenol (1) was treated with acetic anhydride in pyridine to obtain mixed anhydride 3 which was hydrolyzed in situ to acid 4. The latter was esterified with p-methoxybenzyl alcohol (PMBOH) in the presence of N,N′-dicyclohexylcarbodiimide–4-(dimethylamino)pyridine (DCC–...

Acetic anhydride, in the presence of pyridine, reacts quantitatively with anhydrous oxalic acid to form acetic acid, carbon dioxide, and carbon monoxide. Based on this reaction, two small-scale procedures have been devised for the determination of this anhydride. The first, in adaptation of Rosenb...
