MgO/Al2O3 catalyzes the synthesis of azlactone derivatives from condensation reaction of aldehydes (or ketones) with hippuric acid and acetic anhydride as a dehydrating agent under microwave irradiation. The low toxicity, low cost, ease of handling, and high activity of MgO/Al2O3 make this procedure particularly attractive. Also, this catalyst can be easily recovered by decant and can be reused for this condensation five times in succession without considerable loss of its catalytic activity.

, p. 1071 - 1076,6 (2012/12/12)
Simple, effective, and high yield synthetic procedure for the synthesis of 4-ylidene-5(4H)-oxazolones 2a-m from arylidene-malononitriles under solvent-free conditions is described. The scope of this reaction was investigated, and it was found that the presence of anhydrous sodium acetate gave the corresponding oxazolones in excellent yields. The newly generated oxazolone derivative 2m underwent ring transformation into pyrroles, imidazoles, pyridazine, and triazines.
