The title compound, C 30 H 33 NO 4 , was synthesized by the reaction of 2,6-dihydroxybenzaldehyde with p-toluidine and 5,5-dimethylcyclohexane-1,3-dione in glycol under microwave irradition. X-ray analysis reveals that the dihydropyridine ring is in a distorted boat conformation and that the cyclohe

All the interatomic distances in the title compound, C 22 H 25 N 3 O 4 , are normal. The heteroatom ring of the quinoxalinone system shows a half-chair conformation, slightly distorted towards a sofa. In the crystal structure, the molecules dimerize via a pair of N-HÁ Á ÁO hydrogen bonds. The dimers
