Abstract
The new phenols 6-oxo-tingenol, 3-O-methyl-6-oxo-tingenol and 6-oxo-ig uesterol were isolated from the root bark of Maytenus canariensis. The ir structures were determined by H-1 and C-13 NMR spectroscopic studie s, including HMQC, HMBC, DEFT and ROESY and chemical transformations. The synthesis of 6-oxo-tingenol was achieved from tingenone. These com pounds exhibit antibiotic activity against Gram-positive bacteria. Cop yright (C) 1996 Elsevier Science Ltd
