2-hydroxy-3-(1-oxopropyl)-benzoic acid
也就是3-乙酰基水杨酸,
这个东西买不到,小人无能没查到合成方法,
有没有高手帮个忙呀

Abstract
A series of 3'- and 5'-carboxylated chalcones, 6- or 8-carboxylated flavones and 6-carboxylated flavanones, -flavanols and -flavans were prepd. The compds. were tested for their inhibitory activities against leukotriene D4 (LTD4) induced contraction of guinea-pig ileum. A new and convenient synthetic route to 3-acetyl-2-hydroxybenzoic acid, a key intermediate for the synthesis of 3'-carboxy-2'-hydroxychalcones and 8-carboxylated flavones, was developed. The activities of the tested compds. ranged from 0 to 63% inhibition at 10-5 M drug concn. against a single challenge of 10-8 M LTD4. Several compds. were tested in a radioligand binding assay against [3H]LTD4 receptors with pKD-values of 4.95 and 4.83, resp., and are interesting lead structures for the development of rigid LTD4 antagonists. In contrast, the rest of the compds. tested in the binding assay did not show significant displacement of the radioligand, implying that for these compds. the functional activity is probably not caused by competitive antagonism at the LTD4 receptor. The exact mechanism of the relaxant activity remains unclear.

感觉翻译的名字不对吧.应该是3-丙酰基水杨酸吧.
