Procedure
A solution of the tetrahydroxybenzil (see Example 1) (70 mg) in methanol (10 ml) with palladium hydroxide on carbon (20%, 10 mg) was stirred under an atmosphere of hydrogen for 2 hours. The mixture was filtered through Celite, and the solvents removed in vacuo to give an orange gum. Separation by column chromatography over silica gel eluting with 20% ethyl acetate in dichloromethane gave DC-0004 as an off white gum (43 g, 68%).
