The title compound, C 13 H 15 NO 3 , contains a chiral cisdisubstituted oxazine linked to a phenyl ring at the C-2 atom. The racemic crystal structure is stabilized by both intra-and intermolecular C-HÁ Á ÁO hydrogen bonds.
The title compound, C 12 H 14 N 6 , was synthesized via cyclocondensation of 5-guanidino-3-phenyl-1,2,4-triazole with acetone. Only one tautomeric form with the NH H atom vicinal to the methyl groups was observed in the crystal structure. The triazine ring adopts a flattened half-boat conformation.
The title compound, C 18 H 20 ClNO 2 , has been synthesized by the reaction of 4-chlorobenzaldehyde, Meldrum's acid, dimedone and CH 3 NH 3 Cl(NaOAc) in ethanol under microwave irradiation. The pyridone ring adopts a screw-boat conformation and the cyclohexenone ring an envelope conformation.
