Abstract

Recrystallizatfi from ethyl acetate afforded orange crystals, mp 160-162 . The infrared spectrum (chf) had an intense peak at 5.62-5.66 p and a weak band at 6.08-6.11 p . Anal. Calcd. for CI,H&: C, 58.97; H, 4.08; Ac, 37.3. Found: C, 59.13; H, 4.48; Ac, 36.6. Triacetyltetrahydropurpurogallin (XIII).-A solution of 2.2 g. of XI1 in 200 ml. of ethyl acetate containing 2 g. of 10% palladium-~harcoal~~ was shaken under hydrogen (40 lb.) at 80" for a half-hour.
