Herein we describe the first synthesis of the all-L naturally occurring cyclopentapeptides versicoloritides A, B, and C. We found that the extent of oligomerization and epimerization upon head-to-tail cyclization of the linear pentapeptide precursors could be reduced to acceptable levels by modifying the reaction conditions.
