Enamines: Part V - Synthesis of Substituted Phenyl Benzyl Ketones and 2-Arylisatogens

Three different approaches of o/p-nitrophenyl benzyl ketones and their limitation in the synthesis of 2-arylisatogens are described.

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

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.
