说明

呋喃是一种五元杂环化合物，具有高度挥发性、易燃性和潜在致癌物。 它与 2-溴丙烯醛在 oxazaborolidine 催化下发生 Diels-Alder 反应，生成手性 7-oxabicyclo[2.2.1]heptene 衍生物。 已经描述了阳离子双(4-叔丁基恶唑啉)Cu(II) 配合物催化丙烯酰基恶唑烷酮和呋喃之间的对映选择性Diels-Alder 反应得到对映莽草酸。 路易斯酸催化呋喃和一些亲二烯体之间的狄尔斯-阿尔德反应得到取代的环己烯醇和环己二烯醇。

一般描述

Furan is a five membered heterocyclic compound that is highly volatile, flammable and a potential carcinogen. It undergoes Diels-Alder reaction with 2-bromoacrolein catalyzed by oxazaborolidine to yield chiral 7-oxabicyclo[2.2.1]heptene derivatives. Cationic bis(4-tert-butyloxazoline)Cu(II) complex catalyzed enantioselective Diels-Alder reaction between acryloyl oxazolidinone and furan to afford ent-shikimic acid has been described. Lewis acid catalyzed Diels-Alder reaction between furan and some dienophiles affords substituted cyclohexenols and cyclohexadienols.
 

应用

Furan was used in the following processes:
  • Preparation of the starting material required for the synthesis of calix[6]pyrrole.
  • To investigate the kinetics and mechanism of reactions of chlorine atoms with volatile organic compounds.
  • Catalytic transformation of furan to aromatics and olefins.
