Fries rearrangement of substituted phenyl benzoates 1a-j to substituted hydroxy benzophenones 2a-j was achieved in excellent yield. Further benzoylation of 2a-j to benzoyloxy benzophenones 4a-n, a benzophenone analogue was achieved in good yield. All the newly synthesized compounds were evaluated for their anti-inflammatory activity and were compared with standard drugs. Out of the compounds studied
以优异的产率实现了取代苯甲酸苯酯1a-j到取代羟基二苯甲酮2a-j的弗里斯重排。2a-j进一步苯甲酰化为苯甲酰氧基二苯甲酮4a-n,二苯甲酮类似物,收率良好。评价所有新合成的化合物的抗炎活性,并与标准药物进行比较。在所研究的化合物中,对位带有氯和甲基取代基的化合物4c,4e,4g,4h和4k在所有测试剂量下均比标准药物具有更强的活性。
