- Natural Product Chemistry, 140. Synthesis of Some New Acridones
-
Methyl 6-amino-2,3-dimethoxybenzoate (6) which was obtained from 6-formyl-2,3-dimethoxybenzoic acid (1), was treated with phloroglucinol to give two new acridone alkaloids, 1,3,8-trihydroxy-7-methoxy-9-acridone (7) and 1,3-dihydroxy-7,8-dimethoxy-9-acridone (8).Methylation of 7 and 8 gave another four new acridone alkaloids, 1,8-dihydroxy-3,7-dimethoxy-9-acridone (9), 1,8-dihydroxy-3,7-dimethoxy-10-methyl-9-acridone (10), 1-hydroxy-3,7,8-trimethoxy-10-methyl-9-acridone (11) and 1,3,7,8-tetramethoxy-10-methyl-9-acridone (12).
