1,2-Dithiol-3-thiones are a sulfur containing five membered heterocyclic compounds, which constitute an important class of biologically active compounds owing to their ability to release sulfhydryl (SH) group. In this research a new series of multi-cyclic compounds, containing 1,2-dithiol-3-thione moiety, was synthesized. To pursue this goal, five chalcones (1a-e) were synthesized via the condensation of 1-tetralone with aromatic aldehydes under the influence of 5% ethanolic sodium hydroxide solution. These chalcones were converted to β-ketoesters (2a-e) via its reaction with ethyl acetoacetate in presence of 5% ethanolic sodium hydroxide solution. The thionation of these β-ketoesters with phosphorous penta sulfide in xylene afforded the titled compounds (3a-d). The chemical structures of the synthesized compounds were elucidated by the physical and spectral (IR and NMR) data.
1,2-二硫醇-3-硫酮是一种含硫的五元杂环化合物,由于其能够释放巯基(SH)而成为一类重要的生物活性化合物。本研究中,我们合成了一系列新的多环化合物,其中含有1,2-二硫醇-3-硫酮部分。为了实现这一目标,我们利用5%乙醇氢氧化钠溶液的作用,通过1-四氢萘酮与芳香醛的缩合反应,合成了5种查尔酮(1a-e)。这些查尔酮在5%乙醇氢氧化钠溶液的作用下与乙酰乙酸乙酯反应,转化为β-酮酯(2a-e)。这些β-酮酯在二甲苯中与五硫化磷发生硫化反应,得到标题化合物(3a-d)。合成的化合物的化学结构通过物理和光谱(红外和核磁共振)数据得到了阐明。
