摘要：
Two photo-catalytic tandem alkyl radical addition/semipinacol rearrangement reactions of cycloalkanol-substituted styrenes with N-acyloxyphthalimides and O-acyl oximes have been documented. These protocols provide efficient access to functionalized cyclic ketones, and feature mild conditions (i.e., visible light irradiation, redox neutral and room temperature), broad substrate scope and excellent functional group tolerance.

摘要：
Efficient and enantioselective radical difluoroalkylation and perfluoroalkylation reactions of β-ketoesters were successfully developed through an asymmetric photoredox and nickel catalysis cascade. This protocol provides Rf-containing quaternary stereocenters in up to 67% yield and 95:5 er with ethyl iododifluoroacetate and perfluoroalkyl iodides (C3F7I and C4F9I) as radical sources under extremely mild conditions.

摘要：
A visible light-driven photocatalytic generation of sulfonamidyl radicals, and application to intramolecular alkene hydroamination, has been accomplished, providing a mild and efficient approach to various functionalized isoxazolidines. The success of this protocol is based on the strategy of oxidative deprotonation electron transfer by merging the base and the photocatalyst under visible light irradiation, obviating installation of a photolabile handle or stoichiometric external oxidants.

摘要：
A general and efficient Pd/phosphoramidite thioether complex-catalyzed asymmetric N-allylic alkylation of hydrazones with allylic acetates has been developed for the first time. The reaction allows for the preparation of various valuable N-substituted hydrazones with generally good yields and excellent enantioselectivities. Minor structural modification of the ligand resulted in opposite enantiomers, enabling enantiodivergent synthesis of products by the same catalytic system.

摘要：
The activation of inert C(sp~3)–H bonds with control of reactivity and selectivity is one of the central topics in chemical sciences. In this context, alkoxy radical-mediated 1,5- hydrogen atom transfer allows the regioselective transformation of inert C(sp~3)–H bonds to access functionalized molecules which would otherwise be inaccessible. Although some preliminary but elegant results have been disclosed, this chemistry remains challenging and largely underexploited for the following reasons: (1) the bond dissociation energy of O–H bonds is quite high (105 kcal/mol), and therefore the direct formation of alkoxy radicals from alcohols is truly difficult; and (2) the transient alkoxy radicals are too reactive to harness in many cases. Accordingly, various prefunctionalized precursors (e.g., peroxy compounds, nitrite esters, hypohalites, N-alkoxylpyridine-2-thiones, N-alkoxyphthalimides, etc.) are usually employed to generate alkoxy radicals. Despite advances, the development of catalytic approaches for the straightforward conversion of alcohols to alkoxy radicals under mild and environmentally friendly are highly desirable [1].

摘要：
A copper-catalyzed Friedel–Crafts propargylation/hydroamination/aromatization sequence is described. In the presence of a catalytic amount of CuI, this sequential reaction can convert ethynyl benzoxazinanones and indoles into a diverse set of 3,3′-biindoles with high efficiency and selectivity. Moreover, the synthesis of other indole–heteroaryl molecules and the catalytic asymmetric formation of axially chiral 3,3′-biindoles are demonstrated.

摘要：
A dual visible light photoredox and nickel-catalyzed cross-coupling reaction of 2-arylaziridines and potassium benzyltrifluoroborates is described for the first time. This strategy features high functional group tolerance, exclusive regioselectivity for reaction at the more hindered C–N bond, easily accessible substrates, and mild redox-neutral reaction conditions. A variety of diversely substituted β-substituted amines are obtained in generally good yields.

摘要：
Polycyclic indolines are the common and core structural motif of many indole alkaloids that usually exhibit biological activities. Here, we describe two copper-catalyzed cascade reactions between propargylic carbamates and indoles. By doing so, one-step and divergent synthesis of structurally distinct polycyclic indolines, quinoline-fused indolines, C(3a)-indolyl furoindolines, and pyrroloindolines was achieved in high synthetic efficiency and selectivity.

摘要：
Remote control: New strategies for the activation of remote C(sp3 )-H bonds by photoredox-catalyzed (PC) radical translocation via O- and N-centered radicals have recently been described. These methods enable the controlled and site-selective functionalization of inert C(sp3 )-H bonds and provide new opportunities for reaction design (HAT=hydrogen atom transfer).

摘要：
A ligand-free, palladium-catalyzed aminoarylation reaction of the unactivated alkenes in β,γ-unsaturated hydrazones is described. This protocol enables efficient and simultaneous formation of C(sp3)–N and C(sp3)–C(sp2) bonds under mild conditions, providing a practical and general approach to various diversely substituted dihydropyrazoles in generally good yields, without the use of any stoichiometric external oxidant.
