2,4-Disubstituted benzo[b][1,5]thiazepines represent nonfluorescent intense yellow chromophores and are readily synthesized from acid chlorides, terminal alkynes, and ortho-amino thiophenols by a consecutive one-pot three-component Sonogashira coupling-Michael addition-cyclocondensation sequence under mild conditions in good yields.
2,4-二取代苯并[b][1,5]噻嗪是不发荧光的强黄色生色团,可由酰氯、末端炔烃和邻氨基苯硫酚通过温和条件下一锅法连续的 Sonogashira 偶联-迈克尔加成-环缩合反应序列以高产率制备。
