Several 6-methyl-9-carbamoyltetrahydro-4H-pyrido[l,2-a]pyrimid~-4-ones have been prepared using phosgene iminium chloride. These compounds can exist in equilibrium as the cis (3A) imine$(3B) enaminee trans (3C) imine. 'H, 13C and "N NMR prove that the cis-and trans-imine isomers are predominant in t

## 13 C cross-polarization magic angle spinning NMR data are reported for eight derivatives of 4-arylhexahydro-1H,3H-pyrido[1,2-c]pyrimidine-1,3-diones 1-8 and the x-ray diffraction data for 4 with R = 4'-Me. The crystal structure of 4 shows the formation of centrosymmetric dimers via intermolecul
