“…Previous examples of asymmetric S E Ar methods largely follow a mechanistic paradigm wherein an arene nucleophile adds into a prochiral electrophile, with enantiofacial discrimination governed by the catalyst-electrophile complex. [414][415][416] However, the rapidly growing interest in enantiopure atropisomers-compounds that exhibit axial chirality by virtue of hindered rotation about a single bond-for natural products, 417 pharmaceuticals, 418 and catalysis, 81,419 provided an impetus for the development of direct atroposelective S E Ar reactions.…”

Low molecular weight synthetic peptides have been demonstrated to be effective catalysts for an increasingly wide array of asymmetric transformations. In many cases, these peptide-based catalysts have enabled novel multifunctional substrate activation modes and unprecedented selectivity manifolds. These features, along with their ease of preparation, modular and tunable structures, and often biomimetic attributes make peptides well-suited as chiral catalysts, and of broad interest. Many examples of peptide-catalyzed asymmetric reactions have appeared in the literature since the last survey of this broad field in Chemical Reviews (Chem. Rev. 2007, 107, 5759-5812). The overarching goal of this new review is to provide a comprehensive account of the numerous advances in the field. As a corollary to this goal, we survey the many different types of catalytic reactions, ranging from acylation to C-C bond formation, in which peptides been successfully employed. In so doing, we devote significant discussion to the structural and mechanistic aspects of these reactions that are perhaps specific to peptide-based catalysts and their interactions with substrates and/or reagents.
