15. 1H NMR spectrum of the mixture showed no indication of compounds other than the cyclostellettamines. The compounds were identified by their characteristic UV maximum at a wavelength of 267 nm, the measured high resolution mass and their MS fragmentation pattern.
16. [5b]) the name cyclostellettamine G has already been given to the chain length combination 11 and 12, which would have been cyclostellettamine H in our nomenclature.
17. This compound is a synthetic precursor of haliclamine D and has not yet been isolated as a natural product. The name cyclostellettamine Q was chosen because it is probable that further derivatives will be isolated in the future. Cyclostellettamines M, N, O, P and R are reserved for the chain length combinations 9/9, 9/10, 10/10, 9/11 and 11/11, respectively.
