Singlet‐oxygen oxidation of 5‐hydroxymethylfurfural (5‐HMF) was performed in continuous flow mode using rose Bengal as photosensitizer. The resulting butenolide (H 2 MF) was formed selectively in high yield. The procedure proved to be scalable and applicable to related bio‐based furfurals. Furthermore, preliminary data show that H 2 MF can be readily isomerized thermally to 5‐hydroxy‐4‐keto‐pentenoic acid oligomers.
