N.m.r. spectroscopy has been used to determine the stereochemistry of various β-carboxy- and β-hydroxymethylmuconic derivatives. Long-range spin coupling between the olefinic protons is discussed. Isomerisation of the αβ- and γδ-double bonds has been shown to involve participation of the δ- and α-carboxy-groups, respectively. Treatment of both β-carboxy-cis-cis- and cis-trans-muconic acid with hot
Oxygenative cleavage of catechols including protocatechuic acid with molecular oxygen in water catalysed by water-soluble non-heme iron(iii) complexes in relevance to catechol dioxygenases
Catechol dioxygenase model oxygenations have been performed for the first time in water by using water-soluble nonheme iron(III) complexes, enabling the oxygenation of protocatechuic acid and other catechols.

oxidative cleavage to muconic acid using performic acid in an intriguingly safe fashion. Common iron salts were used as catalysts to a level as low as 0.005 mol%, for a maximum turnover number of 13 200. Maximum muconic acidyield reached 84% after isolation by simple filtration. This procedure optimized on catechol was also efficient over a wide range of substituted catechols, providing access to muconolactones
