  2-Aryl-3,4-dihydropyrans as building blocks for organic synthesis: ring-opening reactions with nucleophiles

  摘要：

  An electrophilic ring-opening reaction of 2-aryl-3,4-dihydropyran with many nucleophiles, such as thiophenols, thiols, benzenesulfinic acid, resorcin, 2-methylfuran, benzamide and allyltrimethylsilane, was developed. In the presence of an appropriate catalyst, a product that contains not only a moiety of the nucleophile but also a fragment of 1,3-dicarbonyl compound was obtained. (C) 2011 Elsevier Ltd.

  Nitromethane, a volatile and toxic organic compound, is commonly used as solvent for organic and catalytic reactions. In order to find an alternative for this specific nitro-containing organic solvent, the performance of some nitro-functionalized imidazolium salts such as 1-methyl-3-(4-nitrobenzyl)imidazolium hexafluorophosphate, 1-methyl-3-(4-nitrobenzyl)imidazolium tetrafluoroborate, 1-methyl-3-

  硝基甲烷是一种挥发性和有毒的有机化合物，通常用作有机和催化反应的溶剂。为了找到这种特定的含硝基有机溶剂的替代品，一些硝基官能化的咪唑鎓盐的性能，例如1-甲基-3-（4-硝基苄基）咪唑鎓六氟磷酸盐，1-甲基-3-（4-硝基苄基） ）在一些反应中检测了四氟硼酸咪唑鎓盐，1-甲基-3-（4-硝基苄基）咪唑鎓双（三氟甲磺酰基）酰胺和1,2-二甲基-3-（4-硝基苄基）咪唑鎓六氟磷酸盐，包括醇与六甲基二硅氮烷的三甲基甲硅烷基化， 2-芳基-3,4-二氢吡喃与硫酚或硫醇的开环反应，以及炔烃的铜介导的氧化偶联。如所期望的，这些咪唑鎓盐确实可以在这些反应中代替硝基甲烷。尤其是，咪唑鎓盐与金属催化剂一起，如果涉及的话，可以很容易地回收和再利用而没有明显的活性损失。这些硝基官能化的咪唑鎓盐作为硝基甲烷的替代溶剂的使用，不仅赋予了反应系统绿色的面貌，而且还促进了绿色化学概念下催化系统的合理设计。
