Using a routine procedure, a number of derivatives of the benzo[4,5]isothiazolo[2,3-a]pyrazine-6,6-dioxide ring system have been synthesized from readily available starting materials. A series of chalcones were synthesized, which were subsequently reacted with chlorosulfonic acid to generate chalcone sulfonyl chlorides. The chalcone sulfonyl chlorides were then treated with bromine to generate dibromo
使用常规程序,苯并[4,5]异噻唑并[2,3-a]吡嗪-6,6-二氧化物环系统的许多衍生物已经从容易获得的起始材料合成。合成了一系列查耳酮,随后与氯磺酸反应生成查耳酮磺酰氯。然后用溴处理查耳酮磺酰氯以生成二溴查耳酮磺酰氯。这些随后在沸腾的乙醇中与 1,2-二氨基丙烷和 2-甲基-1,2-二氨基丙烷反应,分别生成化合物 2-10 和 11-19,产率为 12-80%。产物通过光谱分析表征,化合物 11 的最终结构通过 X 射线晶体学确定。筛选合成的化合物对枯草芽孢杆菌的潜在抗菌特性,
