Oxidative conversion of 3-alkoxyfurans to 2-hydroxy-3(2H)-furanones and 2-hydroxy-2-butene-1,4-diones with 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (DDQ) or phenyltrimethylammonium tribromide (PTAB) in t-BuOH

2-Alkoxy-1,3,4-triphenylfurans were oxidized to 3-alkoxy-2,4,5-triphenyl- 2-butene-1,4-diones with 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (DDQ) in t-BuOH. In contrast, various 3-alkoxy-2,4,5-triphenylfurans were directly converted to 2-hydroxy-3(2H)-fu

Convenient transformation of 3-alkoxyfurans to 2-alkoxy-3-furanones or cis-2-alkoxy-2-butene-1,4-diones with phenyltrimethylammonium tribromide

3-Alkoxy-2,5-diphenylfurans and 3-alkoxy-2,4,5-triphenylfurans were converted to 2-alkoxy-3-furanones with phenyltrimethylammonium tribromides(PTAB) in various alcohols at room temperature. The oxidative ring-opening of 3-alkoxy-2,5-diphenylfurans to cis-

Oxidation of furans with 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (DDQ)

2,5-Disubstituted furans were oxidatively cleaved to 2-butene-1,4- diones with DDQ in CH2Cl2-DMSO. In particular, 3-alkoxy-2,5-diphenylfurans were selectively converted into cis-2-alkoxy-1,4-diphenyl-2-butene-1,4-diones with DDQ in C
