Abstract
An efficient and concise synthesis of 5,6-dimethylxanthenone-4-acetic acid(DMXAA) was developed. The overall yield of this 3-step procedure was 82%. The key reaction is the one-step construction of xanthone scaffold between 2,5-dibromo-3,4-dimethylbenzoic acid and 2-hydroxyphenyl-acetic acid assisted by microwave irradiation.
