Article abstract of DOI:10.1016/0008-6215(91)80012-C

Benzoylation of D-galactono (1a), D-glucono (2a), and D-mannono-1,4-lactones (3a), or alkaline treatment of their corresponding perbenzoylated derivatives (1b, 2b, and 3b) afforded the same product: 2,6-dibenzoyloxy-hexa-2,4-dien-4-olide (4).Depending on
