Abstract
Benzylamines belong to an important class of building blocks in the synthesis of biologically active natural products and drugs. Encumbered by amide-directed ortho-C-H activation, remote para-selective C-H functionalization of benzylamines has hitherto not been realized to date. Here, we report a palladium-catalyzed para-selective C-H olefination and acetoxylation of benzylamines using a functionalized benzoyl template. Enhancing the coordination strength of the directing group in the template significantly improved the site selectivity of C-H functionalization.

Abstract
Mono-ortho-arylated arylamines are constituents of various natural products but their syntheses are challenging. This report describes a new synthetic methodology for the ortho-arylation of arylamines and α-aromatic amino acids (phenylglycine and phenylalanine) through a Pd-catalyzed C(sp2)-H activation using the synthetic transient directing group diethoxyethyl-L-proline (DEP). A catalytic amount of diethoxyethyl-L-proline is sufficient to form mono-arylated arylamines as the major products using aryliodides. This method could be useful for the synthesis of various biphenyl amines and novel peptidomimetics.

Abstract
Herein we report the synthesis of imidazo[1,5-a]pyridine heterocycles via a Cu(II)-mediated functionalization of α'-C(sp3)-H bonds of pyridinylaldimines and subsequent cyclization. This strategy exploits the inherent directing ability of heteroleptic aldimine and pyridine groups in the substrate yielding the C-H functionalization of α'-methylene groups in a regioselective fashion over distant methyl or methylene groups in β or γ positions. The observed correlation between the nature of the anionic ligands (halide vs. carboxylate) bonded to copper and the chemoselectivity of the C(sp3)-H activation process points to a concerted metalation-deprotonation pathway prior to cyclization to furnish the corresponding imidazo[1,5-a]pyridine derivative. This copper-mediated C(sp3)-H bond functionalization reaction works for a variety of substrates incorporating linear alkyl chains (from 3 to 12 carbon atoms), and good functional group tolerance (aryl, ether and ester groups). Cu-Catalyzed C(sp2)-H cyanation on the imidazole ring can then take place selectively under oxidative conditions.

Abstract
A series of density functional theory calculations have been carried out to investigate the detailed mechanisms of C-H activation and oxidation reactions, and further to disclose the distinct effects of mononuclear- and binuclear-palladium on these reaction pathways. The results of calculations demonstrated that the C-H activation of 2-phenylpyridine with mononuclear Pd(OAc)2 prefers the inner-shell proton-abstraction mechanism, while that with binuclear Pd2(μ-OAc)4 is biased to the outer-shell proton-abstraction mechanism. The rate-determining free-energy barriers of the two mechanisms were calculated to be 24.2 and 24.8 kcal mol-1, respectively. More importantly, we have simulated the oxidation pathways of PdII → PdIII and PdII → PdIV with strong oxidants including PhI(OAc)2, PhICl2 and NCS, and found that a binuclear PdII-precursor would be oxidized to the corresponding binuclear PdIII-complex while a mononuclear PdII-precursor was deemed to evolve to the corresponding mononuclear PdIV-complex. In addition, the oxidation of PdII with PhI(OAc)2 has been characterized as a radical mechanism, in sharp contrast to the ion-pair mechanism prevalent for the oxidation of PdII with PhICl2. The calculated kinetic and thermodynamic parameters could be qualitatively consistent with the related experimental observations. This molecular modelling can provide valuable insights into the understanding of the distinct effects of the resting state and oxidant on these important transformations.

Abstract
A Pd-catalyzed, meta-selective C-H arylation of nosyl-protected phenethylamines and benzylamines is disclosed using a combination of norbornene and pyridine-based ligands. Subjecting nosyl protected 2-aryl anilines to this protocol led to meta-C-H arylation at the remote aryl ring. A diverse range of aryl iodides are tolerated in this reaction, along with select heteroaryl iodides. Select aryl bromides bearing ortho-coordinating groups can also be utilized as effective coupling partners in this reaction. The use of pyridine ligands has allowed the palladium loading to be reduced to 2.5 mol %. Furthermore, a catalytic amount of 2-norbornene (20 mol %) to mediate this meta-C-H activation process is demonstrated for the first time. Utilization of a common protecting group as the directing group for meta-C-H activation of amines is an important feature of this reaction in terms of practical applications.

Abstract
A Pd(II)-catalyzed enantioselective C-H cross-coupling of benzylamines via kinetic resolution has been achieved using chiral mono-N-protected α-amino-O-methylhydroxamic acid (MPAHA) ligands. Both chiral benzylamines and ortho-arylated benzylamines are obtained in high enantiomeric purity. The use of a readily removable nosyl (Ns) protected amino group as the directing group is a crucial practical advantage. Moreover, the ortho-arylated benzylamine products could be further transformed into chiral 6-substituted 5,6-dihydrophenanthridines as important structural motifs in natural products and bioactive molecules.

Abstract
A method that allows salicylaldehydes to be efficiently transformed into meta-arylated phenol derivatives through a cascade oxidation/arylation/protodecarboxylation sequence is presented. We demonstrate that the aldehyde functional group can be used as a convenient removable directing group to control site selectivity in C-H activation. Aldehydes are easily introduced into the starting materials and the group is readily cleaved after the C-H functionalization event.

Abstract
The commonly used para-nitrobenzenesulfonyl (nosyl) protecting group is employed to direct the CH activation of amines for the first time. An enantioselective ortho-CH cross-coupling between nosyl-protected diarylmethylamines and arylboronic acid pinacol esters has been achieved utilizing chiral mono-N-protected amino acid (MPAA) ligands as a promoter.

Abstract
The first example of palladium-catalyzed ortho-C-H arylation of aryl and benzyl Weinreb amides was developed, in which HOTf was used as a key promoter. This method exhibits good functional group tolerance, a broad substrate scope of both Weinreb amides and aryl iodides, high mono-selectivity and mild reaction conditions.

Abstract
Biaryl skeletons were directly constructed via palladium-catalyzed ortho-arylation of N,N-dimethyl benzylamine with aryl boronic acids with high efficiency and high regioselectivity under open-flask conditions. The N,N-dimethylaminomethyl group was first applied as a directing group in such an oxidative coupling. Various substrates proved to be efficient coupling partners, furnishing the corresponding ortho-monoarylated or -diarylated arenes in moderate to good yields under mild conditions.

Abstract
Salicylic acids are shown to be readily available and versatile starting materials that easily undergo a tandem arylation–protodecarboxylation process under Pd-catalysis. The corresponding meta-arylphenols can subsequently be easily transformed into a variety of meta-functionalized biaryls, highlighting the versatility of this approach to access this structural motif.
