It was synthesized from santonin by base-mediated hydrolysis of a lactone followed by a multistep rearrangement process by R. B. Woodward.[2] Unusually for a carboxylic acid, santonic acid does not form hydrogen-bonded dimers in the crystalline phase. Rather, it adopts a polymeric structure, with individual santonic acid molecules linked by intermolecular carboxyl-to-ketone hydrogen bonds.[1] References ^ a b c A. P. J. Brunskill, H. W.
