4,6-Dihydropyrano[3,2-c][2,1]benzothiazine 5,5-dioxides were synthesized via three-component interaction of 1-ethyl-1H-2,1-benzothiazin-4(3H)-one 2,2-dioxide with active methylene nitriles and cycloalkanecarbaldehydes. The latter were also applied to obtain ammonium salts of 3,3'-(cycloalkylmethanediyl)bis(1-ethyl-1H-2,1-benzothiazin-4-ol) 2,2,2',2'-tetraoxides. The structures of the synthesized compounds
通过1-乙基-1 H -2,1-苯并噻嗪-4(3 H)-的三组分相互作用合成了 4,6-二氢吡喃并[3,2- c ] [2,1]苯并噻嗪5,5-二氧化物。一种带有活性亚甲基腈和环烷甲醛的2,2-二氧化物。后者也用于获得3,3′-(环烷基甲烷二基)双(1-乙基-1 H -2,1-苯并噻嗪-4-醇)2,2,2′,2′-四氧化物的铵盐。合成的化合物的结构通过1 H,13确认13 C NMR以及质谱和元素分析数据。通过单晶X射线衍射研究进一步证实了每一类目标化合物的两个代表结构。筛选合成的化合物的抗菌和抗真菌活性。
