When a-oxocarboxylic acids carrying 8-hydrogens are treated with a secondary amine in boiling benzene with azeotropic removal of water, they decarboxylate quantitatively to form aldehyde-enamines which subsequently are hydrolyzed to the corresponding aldehydes in high yields. a-Oxocarboxylic acids a
