Reactions of Naphthalic Anhydride with β-Benzoylpropionic Acid and Hippuric Acid

Naphthalic anhydride undergoes condensation with β-benzoylpropionic acid and hippuric acid to give α-naphthal-γ-phenyl-crotonolactone (I) and 4-naphthal-2-phenyl-5-oxazolone (II), respectively.Condensation of I and II with aldehydes gives the corresponding arylidenenaphthalides (V) while with hydrazine hydrate and benzylamine, aminonaphthalimide (III) and N,N'-dibenzylnaphthalamide (IV) respectively are formed.
