✦ Synopsis

The selective racemisatlon of an ester in the presence of the corresponding acid has been demonstrated. Phenyl esters me significantly more prone to racemisation than methyl esters. Preliminary results indicate the utility of these results in enzyme-catalysed hydrolysis reactions.

Oxalacetic esters undergo ester exchange at 120' C, at which temperature loss of CO does not occur. A new mechanism Is proposed for the decarbonmonoxylation reaction. The conversion of oxalacetic esters to malonic esters was exploited as early as 1894,3 and remains a useful and well documented proc
