摘要:
By heating the HCl salt of acronycine (1), the new acridone derivatives (6, 9, 13 and 15) were obtained together with noracronycine (2), dihydronoracronycine (3), 1,3-dihydroxy-10-methylacridone (4) and (5). Compound (5), one of the main products of this reaction, is a linear type dihydro derivative of 2, compound (9) is a furanoacridone derivative with a geminal methyl group and compound (15) is a derivative of 5 with an additional C-5 unit.
