Ten azeto[2,1-d][1,5]benzothiazepinone derivatives 6a–j were synthesized starting from 4-acetyl-2-phenyl-1,2,3-triazole 1. First, condensation of 1 with various aldehydes 2a–e afforded α,β-unsaturated carbonyl compounds 3a–e, which subsequently underwent cyclization with o-aminothiophenol to yield the corresponding 2,4-disubstituted-1,5-benzothiazepines 4a–e. Treatment of 4a–e with chloroacetyl chloride
从 4-乙酰基-2-苯基-1,2,3-三唑 1 开始合成了 10 种 azeto[2,1-d][1,5]benzothiazepinone 衍生物 6a–j。首先,1 与各种醛缩合 2a– e 得到 α,β-不饱和羰基化合物 3a-e,随后与 o-氨基苯硫酚环化得到相应的 2,4-二取代-1,5-苯并噻嗪类化合物 4a-e。用氯乙酰氯 5a 或苯氧基乙酰氯 5b 通过 [2+2] 环加成反应处理 4a-e,得到标题化合物 6a-j。通过 1H NMR、MS 和元素分析确定了 6a-j 的结构。
