Syntheses of bryophyte constituents. 8. Sphagnum acid and its degradation products

For Sphagnum acid (1) and its enzymatic degradation product 5-hydroxy-4-(4-hydroxyphenyl)-5H-furan-2-on (2) efficient syntheses on preparative scale were developed. For the (4-hydroxyphenyl)butenolide 2 some characteristic chemical transformations are observed in acidic and basic medium. Johann Ambrosius Barth 1996.
