• -oxazine ring system were successfully synthesized from 5-(4-aminophenyl)-10,15,20-triphenylporphyrin in good yields. The structures of the target products were established on the basis of spectral data and elemental analyses. Keywords: dihydro-1,3-oxazinoporphyrins; iminoporphyrins; La(OTf)3; Mannich

• anticancer significance of these two classes of molecules, it was contemplated to construct new dihydro-1,3-oxazinoporphyrins combining the porphyrin and dihydro-1,3-oxazine moieties in a single molecular framework. Such hybrid compounds may prove useful for pharmacological studies or in the development of
