Abstract
The Rh(I)-catalysed imine-directed oxidative [3 + 2] cycloaddition of benzylamines with maleimides is reported. A wide range of both benzylamines and maleimides is applicable to the reaction. A one-pot three component strategy using benzylamines, 2-pyridinecarboxaldehyde, and maleimides is successfully achieved. Mechanistic studies including deuterium labelling experiments suggest that a zwitterionic intermediate is formed and is a key intermediate through the Rh-catalysed activation of a benzylic C(sp3)-H bond of the imine.

Abstract
The Rh-catalyzed C–H alkylation of benzylamines with alkenes using a picolinamide derivative as a directing group is reported. Both Rh(i) and Rh(ii) complexes can be used as active catalysts for this transformation. In addition, a flow set up was designed to successfully mimic this process under flow conditions. Several examples are presented under flow conditions and it was confirmed that a flow process is advantageous over a batch process. Deuterium labelling experiments were performed to elucidate the mechanism of the reaction, and the results indicated a possible carbene mechanism for this C–H alkylation process. Rh(i)- and Rh(ii)-catalyzed C–H alkylation of benzylamines with alkenes using a picolinamide derivative as a directing group is reported under both batch and flow.![]()

Abstract
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 have 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.

Abstract
![]()
Nature’s catalytic machinery has provided
endless inspiration
for chemists. While the enzymatic ideal has yet to be fully realized,
the field has made tremendous strides toward synthetic, small-molecule
catalysts for a wide array of transformations, often drawing upon
biological concepts in their design. One strategy that has been particularly
influenced by enzymology is peptide catalysis, wherein oligopeptides
are implemented as chiral catalysts in synthetically relevant reactions.
The fundamental goal has been to mimic enzymatic active sites by taking
advantage of secondary structures that allow for multifunctional activation
of substrates within a framework of significantly reduced molecular
complexity. Our group has now been studying peptide-based catalysis
for over
two decades. At the outset, there were many reasons to be concerned
that general contributions might not be possible. Precedents existed,
including the Juliá–Colonna epoxidations mediated by
helical oligopeptides, among others. However, we sought to explore
whether peptide catalysts could find broad applications in organic
synthesis despite what was expected to be their principal liability:
conformational flexibility. Over time, we have been able to identify
peptidic catalysts for a variety of site- and enantioselective transformations
ranging from hydroxyl group and arene functionalizations to redox
and C–C bond forming reactions. The peptides often exhibited
excellent catalytic activities, in many cases enabling never-before-seen
patterns of selectivity. Recent studies even suggest that, in certain
situations, the conformational flexibility of these catalysts may
be advantageous for asymmetric induction. In the course of our
studies, opportunities to employ peptide-based
catalysis to solve long-standing and stereochemically intriguing problems
in asymmetric synthesis presented themselves. For example, we have
found that peptides provide exceptional enantiotopic group differentiation
in catalytic desymmetrization reactions. Early results with symmetrical
polyol substrates, such as myo-inositols and glycerols,
eventually spurred the development of remote desymmetrizations of
diarylmethanes, in which the enantiotopic groups are separated from
the prochiral center by ∼6 Å and from one another by nearly
1 nm. Various hydroxyl group functionalizations and electrophilic
brominations, as well as C–C, C–O, and C–N cross-coupling
reactions using peptidic ligands on copper(I) have now been developed
within this reaction archetype. Additionally, the preponderance of
axially chiral, atropisomeric compounds as ligands, organocatalysts,
and pharmacophores encouraged us to employ peptides as atroposelective
catalysts. We have developed peptide-catalyzed brominations of pharmaceutically
relevant biaryl, non-biaryl, and hetero-biaryl atropisomers that take
advantage of dynamic kinetic resolution schemes. These projects have
vastly expanded the reach of our original hypotheses and raised new
questions about peptide-based catalysts and the extent to which they
might mimic enzymes. Herein, we recount the development and
optimization of these stereochemically
complex reactions, with a particular focus on structural and mechanistic
aspects of the peptide-based catalysts that make them well-suited
for their respective functions. The ability of these peptides to address
important yet fundamentally challenging issues in asymmetric catalysis,
combined with their modularity and ease-of-synthesis, make them primed
for future use in organic synthesis.

Abstract
C–H activation, C–H functionalization, cyclopalladation, mono-protected amino acid, dimeric Pd amino acid complexes, MPAA coordination, relay of stereochemistry.
Mono-protected amino acid (MPAA) ligands are used in a number of Pd-catalyzed C–H functionalization reactions. MPAAs have been proposed to bind to Pd(ii) via κ2-(N,O) coordination, but such binding has not yet been experimentally validated. Herein, we report the synthesis and detailed characterization of a series of MPAA complexes prepared via cyclopalladation of dimethylbenzylamine in the presence of MPAAs. The isolated complexes exist as μ-carboxylato (MPAA) bridged dimers and feature potential M–M cooperativity and secondary sphere hydrogen bonding. Selective MPAA coordination and relay of stereochemistry, previously suggested to uniquely result from κ2-(N,O) MPAA coordination, are both observed. The isolated MPAA complexes undergo C–C and C–X (X = Cl, Br, I) bond formation when treated with electrophiles used for catalytic C–H functionalization. Stoichiometric iodination of MPAA palladacycles was found to proceed via a dinuclear palladium species with one equivalent of iodine in the rate limiting transition structure, and the isolated complexes also served as viable precatalysts for catalytic C–H functionalization. Together, these results provide a number of insights into the reactivity of Pd-MPAA complexes relevant to C–H bond functionalization.

Abstract
Meta-C-H functionalization of benzylamines has been developed using a PdII /transient mediator strategy. Using 2-pyridone ligands and 2-carbomethoxynorbornene (NBE-CO2 Me) as the mediator, arylation, amination, and chlorination of benzylamines are realized. This protocol features a broad substrate scope and is compatible with heterocylic coupling partners. Moreover, the loading of the Pd can be lowered to 2.5 mol % by using the optimal ligand.

Abstract
We present herein an unprecedented, efficient and enantioselective synthesis of triarylmethanes and 1,1-diarylalkanes through N-heterocyclic carbene-catalyzed acylative desymmetrization of bisphenols. This method utilizes readily available substrates, reagents and a simple procedure to deliver the valuable products in excellent enantiopurity. DFT calculations reveal that the selectivity is governed by the C-C bond cleavage step of the tetrahedral intermediate leading to the ester product. A transition state model featuring a combination of intramolecular hydrogen bond and steric effect is developed to explain the enantioselectivity.
