Abstract
Chain walking has been an efficient route to realize the functionalization of inert C(sp3 )-H bonds, but this strategy is limited to mono-olefin migration and functionalization. Herein, we demonstrate the feasibility of tandem directed simultaneous migrations of remote olefins and stereoselective allylation for the first time. The adoption of palladium hydride catalysis and secondary amine morpholine as solvent is critical for achieving high substrate compatibility and stereochemical control with this method. The protocol is also applicable to the functionalization of three vicinal C(sp3 )-H bonds and thus construct three continuous stereocenters along a propylidene moiety via a short synthetic process. Preliminary mechanistic experiments corroborated the design of simultaneous walking of remote dienes.

Abstract
While the hydroboration of alkenes is well established, the corresponding cyclization reaction of dienes remains challenging. Here, we report a new method for hydroboration/cyclization applicable to various 1,n-dienes and hydroboranes. The method features the direct synthesis of borylalkyl cyclopentanes from common 1,6-dienes, which is highlighted by syntheses of elaborated pyrrolidine cores from easily accessible diallylamines. Notably, 1,n-dienes (n > 6) also undergo five-membered ring formation, offering "remote" hydroboration/cyclization that would be otherwise difficult to achieve.

Abstract
An Ir-catalyzed reaction of N-benzylideneanilines with functionalized alkenes such as α,β-unsaturated esters gave ortho-substituted benzaldehyde derivatives with a functional group at the remote position after acidic treatment. The present transformation involves deconjugative long-range isomerization (chain-walking) up to 11 times and C-H activation using an imino group as a transient directing group.

Abstract
A novel method for catalytic remote bismetalation of alkene substrates by the addition of dimetal reagents is accomplished by using chain walking. In the presence of a palladium catalyst, the reaction of various 1,n-dienes and diborons were converted into cyclopentane derivatives with two boryl groups at remote positions via facile regioselective transformation of an unactivated sp3 C-H bond to a C-B bond. Sequential construction of three distant bonds, which is difficult to achieve by any method, was accomplished for the reactions of 1,n-dienes (n ≥ 7).

Abstract
Palladium-catalyzed remote arylative substitution was achieved for the reaction of arylboronic acids with alkenes possessing a distant acetoxy group to provide arylation products having an alkene moiety at the remote position. The use of β-acetoxy elimination as a key step in the catalytic cycle allowed for regioselective formation of unstabilized alkenes after chain walking. This reaction was applicable to various arylboronic acids as well as alkene substrates.

Abstract
Past several decades have witnessed the great evolution of inert C-H bond functionalization reactions as an emerging technique for synthesizing drug molecules, agrochemicals, and functional materials with intricate three-dimensional architectures. Although most activation of "unreactive" C-H bonds was accomplished by exploiting the power of transition metal catalysts, the distant and selective activation of unreactive C-H bonds in an undirected fashion remains one of the critical challenges to this rapidly growing field of organic chemistry. In this context, to meet all these concerns, much more attractive and challenging transition metal catalytic transformations have begun to blossom in recent years with the aid of the chain-walking process. The chain-walking strategy is one of the state-of-the-art techniques in organic synthesis to functionalize the unreactive C-H bonds by allowing the movement of a metal complex along the hydrocarbon chain of the substrate to recognize preferable bond-forming sites. The essential advantage of this strategy is that the bonds are formed only at the places where the catalyst selects for the specific C-H bonds to be cleaved, which not only avoids tedious synthetic procedures for prefunctionalization and the emission of undesirable wastes but also inspires chemists to plan novel synthetic strategies in a completely different manner. Consequently, various C-H bond functionalization reactions have been reported in recent years, employing the vast opportunity provided by this growing field mainly for the acyclic olefinic systems with flexible alkyl chains. Thus, chain-walking reactions allow the reactivity of the reaction centers within the substrates that cannot be realized via the classical mode of reactivity of the substrates. Applying this approach, inexpensive feedstock materials and simple hydrocarbons as an isomeric mixture can be converted to a single isomeric product in a regioconvergent scenario. Simultaneously, the site-selectivity of these reactions can also be switched using a regiodivergent strategy via appropriate tuning of ligands or a slight modification of reaction conditions. Herein, we have provided a comprehensive overview of the chain-walking reactions involving a variety of catalytic systems ranging from the first-row transition metal catalysts to the third-row transition metal catalysts for C-H activation in a concise fashion with the hope for further developments in this area through the appropriate application of the chain-walking reactions.

Abstract
Exploration of novel, three-dimensional chemical space is of growing interest in the drug discovery community and with this comes the challenge for synthetic chemists to devise new stereoselective methods to introduce chirality in a rapid and efficient manner. This Minireview provides a timely summary of the development of palladium-catalyzed asymmetric redox-relay Heck-type processes. These reactions represent an important class of transformation for the selective introduction of remote stereocenters, and have risen to prominence over the past decade. Within this Minireview, the vast scope of these transformations will be showcased, alongside applications to pharmaceutically relevant chiral building blocks and drug substances. To complement this overview, a mechanistic summary and discussion of the current limitations of the transformation are presented, followed by an outlook on future areas of investigation.

Abstract
The operationally simple palladium-catalyzed double-bond migration without heteroatom-containing coordinating functional groups is described. Addition of TaCl5 as a second catalyst greatly enhanced the migration efficiency to provide β-alkylstyrenes through migration of up to a five-carbon chain. Both catalysts were commercially available, and the reaction occurred without external ligands under neutral conditions. The reaction proceeded via generation of π-allyl palladium species, which enabled the chemoselective double-bond migration of hydrocarbons in the presence of allylethers. Remote functionalization through double-bond migration was also demonstrated using FeCl3 as a second catalyst.

Abstract
Chiral macrocyclic receptors 1 with multiple hydrogen-bonding sites in the cavity were synthesized and used as NMR chiral solvating agents (CSAs). The Suzuki-Miyaura cross-coupling reaction gave rapid access to a series of variants 1b-p of unsubstituted parent compound 1a. Among them, 1d with the 4-cyanophenyl group at the 3,3'-positions of the binaphthyl moiety was the most excellent CSA for a benchmark analyte compound, 2-chloropropionic acid (CPA); both of the quartet and doublet signals of CPA were split most completely in CDCl3. Binding constants ( Ka) determined in CDCl3 by NMR titrations indicated that ( R)-1d was the most enantioselective ( Ka( S)/ Ka( R) = 5.4). Interestingly, the Ka value of ( R)-1d for ( S)-CPA (5900) was greater than that of ( R)-1a for ( S)-CPA (3080), which strongly suggests an attractive interaction between the 4-cyanophenyl group of ( R)-1d and ( S)-CPA. The X-ray crystal structure of 1d indicates that one of the two H atoms meta to the cyano group is directed toward the cavity. DFT calculations suggested that this H atom of the 4-cyanophenyl group of ( R)-1d forms a weak hydrogen bond with the Cl atom of ( S)-CPA (C-H···Cl-C hydrogen bond).
