Abstract
In some model experiments aimed at the synthesis of chelidonine, 4b, 10b-dihydro-2,3-methylenedioxy-6H-benzo-[d]naphtho[1,2-b]pyran-6,11 (12H)-dione (2) has been synthesised from homophthalic acid, but attempts to replace the heterocyclic oxygen atom by a nitrogen atom have failed.Keywords
