Carbon-13 labelling study of the methylitaconate ⇄α-methyleneglutarate model rearrangement reaction
Abstract
The model rearrangement mimicking the coenzyme B12-dependent, enzyme-catalysed interconversion of α-methyleneglutaric acid with methyltaconic acid has been carried out with a carbon-13 label demonstrating beyond question that the acrylate group is the migrating group in the model as it is in the enzyme-catalysed rearrangement.
