TL;DR: The use of chiral oxazolines as ligands in asymmetric catalysis has been extensively studied in the literature as mentioned in this paper, with a large number of important publications detailing oxazoline-related chemistry, suggesting that research in this area, as in synthetic organic chemistry in general, has yet to mature.

TL;DR: In this article, the formation of chiral amino alcohols by reduction of amino acids has been the subject of considerable effort due to their importance in asymmetric synthesis? peptide and pharmaceutical chemistry: resolution of racemic mixtures: synthesis of insecticidal compounds: and others.
Abstract: The formation of chiral amino alcohols by reduction of amino acids has been the subject of considerable effort due to their importance in asymmetric synthesis? peptide and pharmaceutical chemistry: resolution of racemic mixtures: synthesis of insecticidal compounds: and others. From the earliest reports by Karrer in 1921, amino alcohols were prepared by reduction of the corresponding amino acid esters with sodium in ethanol.& Subsequently, lithium aluminum hydride6b and sodium borohydride& were employed and furthermore, free amino acids were shown to be reduced directly by sodium bis(2-methoxyethoxy)aluminum hydride? the borane-dimethyl sulfide complex activated by boron trifluoride-etherate,w lithium aluminum hydride? lithium borohyride with trimethylchl~rosilane,~~ sodium borohydride-trimethyl~hlorosilane,~g or boron trif l~orideetherate.~~ Very recently, while this manuscript was being prepared, a report appeared describing an efficient reduction of amino acids and derivatives using sodium borohydride and sulfuric

TL;DR: An overview of the basic photophysics and electron transfer theory is presented in order to provide a comprehensive guide for employing this class of catalysts in photoredox manifolds.
Abstract: In this review, we highlight the use of organic photoredox catalysts in a myriad of synthetic transformations with a range of applications. This overview is arranged by catalyst class where the photophysics and electrochemical characteristics of each is discussed to underscore the differences and advantages to each type of single electron redox agent. We highlight both net reductive and oxidative as well as redox neutral transformations that can be accomplished using purely organic photoredox-active catalysts. An overview of the basic photophysics and electron transfer theory is presented in order to provide a comprehensive guide for employing this class of catalysts in photoredox manifolds.

TL;DR: P palladium and ruthenium catalysts have been described that enable the direct arylation of (hetero)arenes with challenging coupling partners--including electrophilic aryl chlorides and tosylates as well as simple arenes in cross-dehydrogenative arylations.
Abstract: The area of transition-metal-catalyzed direct arylation through cleavage of CH bonds has undergone rapid development in recent years, and is becoming an increasingly viable alternative to traditional cross-coupling reactions with organometallic reagents In particular, palladium and ruthenium catalysts have been described that enable the direct arylation of (hetero)arenes with challenging coupling partners—including electrophilic aryl chlorides and tosylates as well as simple arenes in cross-dehydrogenative arylations Furthermore, less expensive copper, iron, and nickel complexes were recently shown to be effective for economically attractive direct arylations
