Novel molecular matrices have been derived from coumarin-4-acetic acids and β-phenylethylamines using the Bischler–Napieralski protocol which has led to the synthesis of analogues of tetrahydropapaverine in which the dimethoxybenzene moiety has been replaced by substituted coumarins. One carbon homologation has led to cyclization at the C3 position of coumarin generating the protoberberine skeleton
