Alpha-helix and mixed 3(10)/alpha-helix in cocrystallized conformers of Boc-Aib-Val-Aib-Aib-Val-Val-Val-Aib-Val-Aib-OMe. [PDF]

open access: yesProceedings of the National Academy of Sciences, 1989
Two molecules of Boc-Aib-Val-Aib-Aib-Val-Val-Val-Aib-Val-Aib-OMe (where Boc is t-butoxycarbonyl and Aib is alpha-aminoisobutyryl) cocrystallize in a triclinic cell with different helical conformations. One molecule is completely alpha-helical with seven 5----1 intramolecular hydrogen bonds. It forms three head-to-tail NH...O = C hydrogen bonds to other
