addition, bearing a 2-thienyl group at the 3-position, gave the only addition adduct at room temperature in 3 h, whereas the chalcones bearing the 2-furyl group at the 1-position gave an addition-cyclization product (1, 4-thiazepine) in the same conditions. The effect of the groups to the reaction was investigated by changing the 1- and 3-position groups. The chalcones bearing the 2-thienyl group at the 1-position
摘要研究了三乙胺介导的 2-氨基乙硫醇盐酸盐向查耳酮类似物的加成。这种加成,在 3-位带有 2-噻吩基,在室温下 3 小时内产生唯一的加成物,而在 1-位带有 2-呋喃基的查耳酮产生加成环化产物(1, 4-噻嗪)在相同条件下。通过改变1-和3-位基团来研究这些基团对反应的影响。在 1 位带有 2-噻吩基的查耳酮和其他化合物在室温下提供不同比例的产物混合物 0.5-24 小时。此外,在回流条件下在 36 小时内获得了加成环化产物(1,4-硫氮杂)。通过1H NMR、13C NMR、红外和元素分析阐明了合成化合物的结构。
