Total synthesis of cyclomarin C

Wen, Shi-Jun,Yao, Zhu-Jun

, p. 2721 - 2724 (2007/10/03)

The total synthesis of cyclomarin C was accomplished through a convergent strategy from a tetrapeptide fragment and a tripeptide one. The developed methods to prepare the needed noncoded amino acids, the proper protection of peptide fragments, and identification of the optimum macrocylization site can be applied to further synthetic studies on other members of cyclomarins.
