Homologous 4,5-dihydro-5-thioxo-1H-tetrazole-l-alkanoic and alkanesulfonic acids were prepared by reaction of sodium azide with methyl (carboxyalkyl)- and (sulfoalkyl) carbamodithioates, respectively. 4,5-Dihydro-5-thioxo-1H-tetrazole-i-alkanamides were derived from the corresponding alkanoic acids by aminolysis of their acid chlorides or imidazolides. Analogous alkane-sulfonamides were synthesized
通过叠氮化钠分别与(羧烷基)-和(磺烷基)氨基甲酸二硫代甲烷酯反应,制备同源的4,5-二氢-5-噻吩-1- H-四唑-1-链烷酸和链烷磺酸。通过相应的链烷酸的酰氯或咪唑化物的氨解反应,可以从相应的链烷酸衍生得到4,5-二氢-5-噻吩-1 H-四唑-1-烷基酰胺。通过[[[(((1,1-二甲基乙基)氨基]磺酰基]-烷基氨基甲酸二硫代甲基酯与叠氮化钠的反应,然后用三氟乙酸除去1,1-二甲基乙基,合成了类似的烷烃-磺酰胺。
