The Intracavity Extension of 28-Hetero-2,7-naphthiporphyrins in Reactions with Alkylamines.

The 28-hetero-2,7-naphthiporphyrins reacted with triethylamine and diethylamine to form nonaromatic intracavity-extended macrocycles incorporating naphthodihydro-2-pyran, naphthotetrahydropyridine, and naphthopyrrolotetrahydro-1-azepine moieties. The new macrocycles were characterized in solution by means of NMR and UV-vis spectroscopy and in the solid state by XRD.
