Abstract

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).
