Abstract

Concise total syntheses of the anthracenone C-glycosides alvaradoins E and F, uveoside, and 10-epi-uveoside (1-4) have been accomplished from chrysophanic acid 8 and bromosugar 9. Key steps in the syntheses include the DBU-induced coupling of 8 and 9 to produce β-C-glycoside 11, and a Pb(OAc)4-mediated Kochi reaction to introduce the C-1' oxygen atom of the natural products. Isothermal titration calorimetry and fluorescence binding studies reveal that compounds 1 and 2 have good affinity for the plasma protein HSA.
