General description: 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.
Application: 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.
