Indoline‐Based Constrained Peptidomimetic Motifs Obtained via the Joullié–Ugi Reaction of Indolenines

Abstract

Sterically demanding indolenines were employed as cyclic imine substrates in the Joullié–Ugi reaction with diverse isocyanides and carboxylic acids resulting in a new type of conformationally constrained indoline‐based peptidomimetic compounds.
