Available (2-aryl-5-mesyl-1,3-oxazol-5-yl)triphenylphosphonium salts readily react with sodium thiophenolates and their heterocyclic analogs by way of substitution of the mesyl group by an arylsulfanyl or a heterylsulfanyl group. Treatment of the products with sodium hydroxide results in their mild dephosphorylation, which was used for preparative synthesis of a series of 2-aryl-5-arylsulfanyl(heterylsulfanyl)-1,3-oxazoles.
现有的(2-芳基-5-甲磺酰基-1,3-恶唑-5-基)三苯基鏻盐很容易通过甲磺酰基或杂磺酰基取代甲磺酰基的方式与噻吩酸钠及其杂环类似物发生反应。用氢氧化钠处理这些产物可使其温和地去磷酸化,从而用于制备一系列 2-芳基-5-芳硫基(杂硫基)-1,3-恶唑的合成。
