Abstract
The synthesis of the 2,6-diphenyldpiperidin-4-one derivative of the title compound, 4,4a,5,6,7,8-hexahydro-4a-methyl-2,5,7-triphenyl-2H-pyrido[4,3-d][1,3]oxazine (HMTPO), was developed using the reaction of 4-hydroxy-3-methyl-2-butanone, benzaldehyde, and ammonium acetate in ethanol as a solvent. The molecular structure of HMTPO was determined by single-crystal X-ray diffraction. The chemical structure was confirmed by employing IR, 1H NMR, 13C NMR, and mass spectral data. To gain deeper insight into the bonding interactions within the compound, Hirshfeld surface analysis and two-dimensional fingerprint plots were conducted. The findings reveal that the Hirshfeld surfaces are predominantly influenced by H···H and C···H contacts, highlighting the significant role these interactions play in the compound’s overall stability and structural configuration.
