ALDEHYDE-ENAMINES FROM α-OXOCARBOXYLIC ACIDS. A FACILE AND GENERAL ROUTE TO ALDEHYDES VIA DECARBOXYLATION OF α-OXOCARBOXYLIC ACIDS CARRYING β-HYDROGENS

Stamos, Ioannis K.

, p. 459 - 462 (1982)

When α-oxocarboxylic acids carrying β-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.
