diastereomeric scaffoldsProM-3 and ProM-7 were stereoselectively synthesized (as 9-fluorenylmethoxycarbonyl derivatives), and their configuration was unambiguously proven by means of X-ray crystallography. The required dehydroisoleucine building blocks were prepared by applying the enantioselective Kazmaier–Claisen rearrangement. The target compounds represent dipeptide analogs rigidified in a PPIIhelix conformation
