 Title    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.

 Title    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).

 Title    Synthese und Struktur von Prolinring-modifizierten Actinomycinen des X-Typs Synthesis and Structure of Proline Ring Modified Actinomycins of the X-Type  
 Abstract    The first total synthesis o f actinomycins containing L-4-hydroxyproline (1) and the separa­ tion and NM R spectroscopic assignment o f the regioisomers X (V* and iso-X0/i (lc, le) are described. The synthetic X 0/j proves, that the oxidized proline ring of the natural actinomycins
