The synthesis of thiolactime 4 and first studies on the syntheses of other thiolactimes with different substituted thieno[2,3-b][1,4]thiazine moieties are described as well as the syntheses of structurally modified amidines 10 - 14 with the same basic structure. The thieno[2,3-b][1,4]thiazine derivatives were prepared by reacting methyl 5-chloro-4-nitro-2-thiophencarboxylate with ethyl thioglycolate
描述了巯基乙酸4的合成以及其他具有不同取代的噻吩并[2,3-b] [1,4]噻嗪部分的巯基噻吩的合成的初步研究,以及具有相同碱性的结构修饰的am 10-14的合成。结构体。噻吩并[2,3-b] [1,4]噻嗪衍生物的制备方法是,使5-氯-4-硝基-2-噻吩甲酸甲酯与硫代乙醇酸乙酯反应,然后还原环化成6,先将其皂化然后处理用Lawesson试剂获得巯基内酰胺8或直接与巯基内酰胺9反应。9与各种胺反应得到所需产物10-14,将其对NO合酶抑制活性进行药理学测试。
