Abstract

There are a large number of studies on sponges from warm or tropical waters, whereas little is known about the chemistry of sponges from Arctic waters. Here, we describe the isolation and structure elucidation of two new 3‐alkyltetrahydropyridine alkaloids (haliclamines C and D) from the Arctic sponge Haliclona viscosa. MS and 2D NMR spectroscopy were used to analyse the structure of the two new compounds. Since the haliclamines consist of long alkyl chains, MS/MS methods were necessary for the unambiguous assignment of the constitution of the new alkaloids. (© Wiley‐VCH Verlag GmbH & Co.
