Abstract
Two tripeptides of the type Boc-Pro-delta ZX-Gly-NHEt (where X = Leu, Phe) have been synthesized and their solution conformations investigated by 270 MHz 1H n.m.r. and i.r. spectroscopy. These conformational studies indicated that delta ZLeu, similar to delta ZPhe, has a strong tendency to stabilize folded Type II beta-turn conformations when present at i + 2 position.
