To understand the terminal effect of chiral residue for determining a helical screw sense, we adopted five kinds of peptides I-V containing N-and/or C-terminal chiral Leu residue(s): Boc-D-Leu-(Aib-⌬Phe) 2 -L-Leu-OMe (IV), and Boc-D-Leu-(Aib-⌬Phe) 2 -Aib-OMe (V). The segment -(Aib-⌬Phe) 2 -was used

## Abstract The preferred conformation of three __N__^α^‐acetylated Aib/Iva host/guest pentapeptide esters and their __N__^α^‐benzyloxycarbonylated synthetic precursors, prepared by solution methods and fully characterized, were examined in chloroform solution using FT‐IR absorption and ^1^H‐NMR an
