When ethylene glycol is condensed with an a-diketone (R-CO-CO-R) in an acid catalyzed reaction, a mixture of two isomers is usually obtained (2). Interestingly enough, the structural assignments of the parent compounds (R-H), Isomers A and B, were a matter of dispute over a period of more then thirt
