A method of synthesizing for 3, 6-disubstituted 2, 9-dioxo-2, 3, 6, 9-tetrahydrothiazolo-[5, 4-f] quinoline-8-carboxylic acids via the thiazolium salts was studied and proved to be practical. The reactions of the thiazolium salt with various nucleophilic reagents afforded several new derivatives. Gould-Jacobs reaction of the benzothiazole-2-ones and benzothiazole-2-thione derivatives were also carried out.
研究并证明了通过噻唰盐合成3,6-二取代-2,9-二氧-2,3,6,9-四氢噻唑并[5,4-f]喹啉-8-羧酸的方法是切实可行的。噻唑盐与各种亲核试剂的反应得到了几种新衍生物。还进行了苯并噻唑-2-酮和苯并噻唑-2-硫酮衍生物的Gould-Jacobs反应。
