Popis:	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)‐furanone with phenyltrimethylammonium tribromide (PTAB) in t‐BuOH. The oxidative ring opening of 3‐alkoxy‐2,5‐diphenylfurans to cis‐2‐hydroxy‐2‐butene‐1,4‐dione was also accomplished with PTAB in t‐BuOH under the same reaction conditions.
