  Synthesis and easy aromatisation of 5-substituted 6-(alkylthio)-2-methoxy-2,3-dihydropyridines. A new approach to the pyridine ring

  摘要：

  Reaction of lithiated methoxyallene, 1-ethoxyethoxyallene, 1-(methylthio)propyne and 2-butyne with methoxymethyl isothiocyanate, MeOCH2N=C=S followed by methylation affords the imidothioates H2C=C=C(R)C(SMe)=NCH2OMe [R=Me, OMe, OCH(Me)OEt, SMe]. Rearrangement to the fully conjugated Systems H2C=CH-C(R)=C(SMe)-N=CHOMe and subsequent electrocyclisation of these compounds leads to the 5-substituted 6-(methylthio)-2-methoxy-2,3-dihydropyridines with good to excellent yields. In the presence of acidic catalysts or by heating at elevated temperatures these dihydropyridines eliminate methanol to afford 3-substituted 2-(methylthio)pyridines. The aroma compound 2-(methylthio)-3-pyridinol was obtained by acid-catalysed treatment of 3-(1-ethoxyethoxy)-2-(methylthio)pyridine. (C) 2002 Elsevier Science Ltd. All rights reserved.

  cyclopropylmethylthio groups can be easily introduced into the aromatic rings from the corresponding S-[2-(dimethylamino)ethyl]isothiourea dihydrochloride and S-cyclopropylmethylisothiourea hydrobromide. The possible reaction mechanism is proposed. It is believed that this route to aryl alkyl sulfides is well competitive with currently known methods due to its wide substrate scope, excellent yields, easy

  在碳酸铯的存在下，开发了通过芳基卤化物与可商购的S-甲基异硫脲硫酸盐反应的有效合成芳基甲基硫醚的方法。这种无味且高度结晶的固体可用作恶臭甲硫醇的替代品。在不使用柱色谱分离的情况下，克级反应也可以顺利进行。类似地，2-（二甲基氨基）乙硫基和环丙基甲硫基可容易地从相应的S- [2-（二甲氨基）乙基]异硫脲二盐酸盐和S中引入芳环。-环丙基甲基异硫脲氢溴酸盐。提出了可能的反应机理。据信，由于其广泛的底物范围，优异的收率，易于操作和无过渡金属的条件，该制备芳基烷基硫化物的方法与目前已知的方法具有很好的竞争性。
