Abstract:
Grandinal, a new dimeric phloroglucinol compound, was isolated from Eucalyptus grandis and characterized by spectral techniques. Tautomeric structures 1, 2, and 3 were assigned to grandinal. Biogenetically, 1 is proposed to be formed from intermediates derived from grandinol and jensenone.
