| A New Antibiotic Chloro-Sesquiterpene from the Caribbean Sponge Smenospongia aurea  | | | | Abstract
| A new sesquiterpene phenol, containing the rather uncommon chlorine atom, was isolated from a sample of Smenospongia aurea collected along Baham a's Islands. Its structure has been elucidated by spectroscopic analysis and confirmed via synthesis. This com pound exhibited antibacterial activity. | | | |

| Octacidomycine, IV : Neue Totalsynthese von rac-Octacidomycin und strukturverwandten Oligocarbonsäuren Octacidom ycins, I V : A New Total Synthesis of rac-O ctacidom ycin and Structurally R elated O ligocarboxylic A cids A ndreas K rause, H elm ut | | | | Abstract
| a new strategy, an improved total synthesis of the unique antibiotic octacidomy-cin (1) and of structurally related oligocarboxylic acids was developed (Scheme 1,2). Starting from 3 and the tetraethylester of l,17-dibromo-6,6,12,12-heptadecane-tetracarboxylic acid (6) as a key compound, systematical fragment condensations lead to the nonatriacontane-pentadecacarboxylic acid 11 and hence to the 1,3,9,15,21,27,33,39-nonatriacontane-octacarbo-xylic acid 1. The synthetic pathway can easily be modified and generally be applied for the synthesis of a broad variety of hitherto unknown oligocarboxylic acids or their esters, respec tively, and even of cyclic analogues (Scheme 2). | | | |
