peptidyl oxazoline strand and positions the valine side chains in either pseudoaxial or pseudoequatorial orientations. In the former case, transannular strain prevents the formation of 12-membered cyclopeptidealkaloids. Several X-ray structures illustrate the conformational preferences in this family of marine natural product analogs.
