homo‐dipeptide alkylamide sequences via a solution‐phase Ugi multicomponent reaction approach. The conformers of these peptides have been determined in the crystalline state by X‐ray diffraction to distinguish the influences of the C‐terminal substituent. One of the Adm peptides folds into an open and a hydrogen‐bonded γ‐turn geometry. Moreover, 3D‐structures have been observed featuring two consecutive

(electron donor-acceptor) complexes provides a mild platform for aryl-radical-mediated halogen atom transfer activation of a wide range of functionalized alkyl iodides, including tertiary alkyl iodides. Using an aryl sulfonium salt with carbonate as an inexpensive donor for EDA complex formation, the general reaction platform has been applied in a divergent, metal-free photochemical approach to nitriles
