ABSTRACT:
Process for preparing a 2-hydroxy-butenoic acid derivative of the general formula, ##STR1## wherein R.sup.1 is a group selected from aliphatic, alicyclic or aromatic radicals and R.sup.2 is a lower alkyl group by heating a glycidic acid derivative having the general formula, ##STR2## wherein R.sup.1 and R.sup.2 is as defined above or for preparing a pyruvic acid derivative of the general formula, ##STR3## wherein R.sup.1 and R.sup.2 are as defined above by heating the glycidic acid derivative of the above mentioned formula (I) or the 2-hydroxy-butenoic acid derivative of formula (II) in the presence of an electrophilic agent.
