The Reaction of Piperazine-2,5-dione with 2-Formylbenzoic Acid

Reaction of piperazine-2,5-dione with 2-formylbenzoic acid in the presence of triethylamine gives three products: 1-(3'-oxo-1',3'-dihydroisobenzofuran-1'-yl)piperazine-2,5-dione, its 1,4-bis analogue which had previously been identified as the 3,6-compound, and 2,2'-3,6-dioxopiperazine-2,5-diylidenebis(methylidyne)bis(benzoic acid).The latter compound is shown by 1H and 13C n.m.r. spectroscopy to be the Z,Z isomer.
