Reaction Steps
The alcohol of Example 20 (35 mg) was treated with 130 mg of dicyclohexylcarbodiimide and 0.4 ml of trifluoroacetic acid and 3 ml of dimethyl sulfoxide for 3 hours and then extracted several times with benzene. Evaporation of the benzene layers produced brown-red 5,7,12-trihydroxy-1,2,3,4,6,11-hexahydro-2,6,11-trioxonaphthacene (formula 18), m.p. above 300° C., infrared maximum 1730 cm-1).
