Synthesis of 8-benzylamino-1,2-dihydro-10-oxo-2,2,5-trimethyl-4H-pyrano[4′3′∶4,5]pyrido[3,2-e]-1,3-thiazine and its psychotropic activity

5]pyrido[3,2-e]-l,3-thiazine, and studied some of its psychotropic properties. As the starting compound we used the previously described [3] 3,4-dihydro-5-carbamoyl-3,8,8-trimethyl-6-chloro-lHpyrano-[3,4-c]pyridine (I). The reaction of amide I with sodium nitrite in the presence of hydrochloric acid gave acid (I]), which was further converted into acid chloride 0II). Treatment of the latter with ammonium
关于吡啶并[3,2-e]-1,3-噻嗪衍生物的文献资料很少。只有其 3-酰基-、3-氨基-和 3-氨基甲酰基衍生物是已知的 [1, 2]。尚未描述吡喃并 [4', Y:4,5] 吡啶并 [3,2-e]-l,3-噻嗪系统。在我们继续研究寻找新的生物活性化合物 [3, 4] 的过程中,我们进行了 1,2-二氢-4H-吡喃并 [4',3' 的新杂环系统代表的合成: 4,5]吡啶并[3,2-e]-l,3-噻嗪,并研究了它的一些精神作用。我们使用先前描述的 [3] 3,4-二氢-5-氨基甲酰基-3,8,8-三甲基-6-氯-1H吡喃并-[3,4-c]吡啶(I)作为起始化合物。在盐酸存在下酰胺 I 与亚硝酸钠反应得到酸 (I]),其进一步转化为酰氯 0II)。
