F. Cafieri et al., 6-BROMO-5-HYDROXY-3-INDOLECARBOXYALDEHYDE FROM THE CARIBBEAN SPONGE OCEANAPIA-BARTSCHI, Zeitschrift fur Naturforschung. B, A journal of chemical sciences, 48(10), 1993, pp. 1408-1410
The organic extract from Oceanapia bartschi has been shown to contain
the antibiotic diterpene Ambliol A (1) and three indole derivatives, 3
-bromoindole (2), 6-bromo-3-indolecarboxyaldehyde (3), and 6-bromo-5-h
ydroxy-3-indolecarboxyaldehyde (4). The structure of the novel compoun
d 4 has been established from its spectroscopic (H-1 and C-13 NMR, UV,
IR, and MS) data.
