Abstract
Copper-catalyzed enantioselective coupling has been widely investigated, which allows rapid construction of various chiral molecules. Despite important advances via polar and radical mechanisms, exploring general and practical strategies for the regio-, enantio- and diastereoselective assembly of stereogenic centers is of significant value but remains highly problematic. The integration of photocatalysis with asymmetric copper catalysis could provide appealing access to the development of new reaction pathways and structurally diverse chiral compounds, and extend the boundaries of radical chemistry. This review summarizes recent advances in photoinduced copper-catalyzed enantioselective coupling reactions, and discusses the mechanistic aspects.

Abstract
Amines featuring an adjacent stereocenter are important building blocks, and recent years have seen remarkable growth in methods forming these via prochiral α-amino radical intermediates. However, very few can exert control over the newly formed stereocenter. We disclose a strategy to overcome this in the context of one of the most widely used radical carbon-carbon bond forming reactions, the Giese reaction. Incorporation of a removable basic heteroarene into the substrate enables a network of attractive noncovalent interactions between a phosphoric acid catalyst, the subsequently formed α-amino radical, and the Giese acceptor, allowing the catalyst to exert control during the C-C bond forming step. Deprotection of the products leads to analogues of γ-aminobutyric acid. We anticipate that this strategy will be applicable to other asymmetric radical transformations in which catalyst control is presently challenging.

Abstract
Intermolecular photocatalytic hydroaminoalkylation (HAA) of alkenes have emerged as a powerful method for the construction of alkyl amines. Although there are some studies aiming at stereoselective photocatalytic HAA reactions, the alkenes are limited to electrophilic alkenes. Herein, we report a highly regio-, diastereo-, and enantioselective HAA of electron-rich dienol ethers and α-amino radicals derived from α-amino acids using a unified photoredox and palladium catalytic system. This decarboxylative 1,2-Markovnikov addition enables the construction of vicinal amino tertiary ethers with high levels of regio- (up to >19 : 1 rr), diastereo- (up to >19 : 1 dr), and enantioselectivity control (up to >99 % ee). Mechanistic studies support a reversible hydropalladation as a key step.

Abstract
The development of new synthetic methods involving radical intermediates to control the absolute configuration of newly formed stereocenters has seen unprecedented growth in the past few decades. Despite significant advances in this topic, catalytic asymmetric direct construction of stereocenters through addition of radicals to internal alkenes is of special interest due to its potential to simultaneously build (more than) two consecutive stereogenic centers. Methodologies such as chiral Lewis acid catalysis, organocatalysis, and transition metal catalysis have been successfully leveraged to exert enantiocontrol in this challenging domain. This tutorial review highlights the recent significant progress in the realm of rapidly and conveniently building enantioenriched stereocenters via addition of radicals to internal alkenes, with an emphasis on mechanistic scenarios governing the absolute stereochemistry and unmet challenges in this emerging and promising field.

Abstract
AbstractThis short review presents an overview of visible-light-driven asymmetric catalysis by chiral complexes of first-row transition metals. The processes described here include dual catalysis by a chiral complex of copper, nickel, cobalt, or chromium and an additional photoredox or energy-transfer catalyst, and bifunctional catalysis by a single chiral copper or nickel catalyst. These methods allow valuable transformations with high functional group compatibility. They provide stereoselective construction of carbon–carbon or carbon–heteroatom bonds under mild conditions, and produce a diverse range of previously unknown enantioenriched compounds.1 Introduction2 Nickel-Based Photocatalytic Asymmetric Catalysis3 Copper-Based Photocatalytic Asymmetric Catalysis4 Photocatalytic Asymmetric Catalysis by Chiral Complexes of Cobalt or Chromium5 Conclusion
