Abstract
Abstract The synthesis of the decaendothiopeptide BOC-Trp-Ile-Ala-Aib-Ile-ValΨ[CSNH]Aib-Leu-Aib-Pro-OMe is described. The introduction of the thioamide group next to the bulky Aib occurred via a variation of the ‘azirine/oxazolone method’ without epimerisation. The structure of the decaendothiopeptide was etablished by single-crystal X-ray crystallography, thereby two types of helices could be observed.
