and their N-methyl analogues were readily prepared from the corresponding 5-bromo-1,3-benzothiazol-2(3H)-ones by means of Stille and Suzuki reactions. The compounds were substituted at the C-5 position with vinyl, acyl, or aryl groups optionally carrying electron-withdrawing or electron-donating substituents. heterocycles - coupling - catalysis - benzothiazolones - Stille reaction
借助Stille和方法,由相应的5-溴-1,3-苯并噻唑-2(3 H)-很容易地制备5-取代的1,3-苯并噻唑-2(3 H)-及其N-甲基类似物。铃木的反应。所述化合物在C-5位被乙烯基,酰基或芳基取代,所述乙烯基,酰基或芳基任选地带有吸电子或供电子取代基。 杂环-偶联-催化-苯并噻唑酮-Stille反应
