reaction to the phenanthryl ketones 1a–d led to the thiomorpholides 2a–d, hydrolysis produced the acids mentioned in the title. An alternative route, of much better yield, was based on the oxythallation of 1a–d to give the methyl arylacetates 4a–d, which were saponified to 3a–d. Among these four acids, only 3b showed an antiinflammatory activity approaching that of Fenbufen.
Willgerodt-Kindler 反应对菲基酮 1a – d 的应用导致了硫代吗啉 2a – d,水解产生了标题中提到的酸。另一种产率更高的路线是基于 1a – d 的氧合生成芳基乙酸甲酯 4a – d,然后将其皂化为 3a – d。在这四种酸中,只有 3b 显示出接近芬布芬的抗炎活性。
