Reaction of 2-(m-Tolyl)-4-arylmethylene-2-oxarolin-5-ones with amines
Keyword(s):
A facile route for the preparation of 1,2-diaryl-4-arylmethylene-2-imidazolin-5-ones was established by the direct interaction of primary aromatic amines with 2-(m-tolyl)-4-arylmethylene-2-oxazolin-5-ones in acetic acid containing catalytic amounts of sodium acetate. The same imidazolones were also obtained by cyclization of the aryl- carboxamides of α-arylcarboxamido-β-arylacrylic acids under the same reaction conditions. A possible reaction mechanism was discussed.
