The formation of carbon-nitrogen bonds for the preparation of aromatic amines is among the top five reactions carried out globally for the production of high-value materials, ranging from from bulk chems. to pharmaceuticals and polymers. As a result of this ubiquity and diversity, methods for their preparation impact the full spectrum of chem. syntheses in academia and industry. In general, these mols. are assembled through the stepwise introduction of a reactivity handle in place of an aromatic C-H bond (i.e., a nitro group, halogen or boronic acid) and a subsequent functionalization or cross-coupling. Here we show that aromatic amines can be constructed by direct reaction of arenes and alkyl amines using photocatalysis, without the need for pre-functionalization. The process enables the easy preparation of advanced building blocks, tolerates a broad range of functionalities, and multigram scale can be achieved via a batch-to-flow protocol. The merit of this strategy as a late-stage functionalization platform has been demonstrated by the modification of several drugs, agrochems., peptides, chiral catalysts, polymers and organometallic complexes.

Authors report the first asym. three-component nucleophilic addition/dearomative [4+2] cycloaddition/isomerization cascade of transient dipoles generated from N-heteroarenes and allenoates with methyleneindolinones in the presence of chiral N,N’-dioxide/metal complexes. This tandem reaction enabled rapid access to versatile chiral polycyclic N-heterocycles with good to excellent enantioselectivities under mild reaction conditions in spite of the strong background reaction, including 1,2-dihydroisoquinoline, 1,2-dihydropyridine derivatives, and others. Meanwhile, a series of control experiments were conducted to elucidate the reaction mechanism and the roles of additives.

A three-component Minisci reaction coupling of 1,3-dicarbonyl compounds with vinyl ethers and quinolines or isoquinolines under visible light is developed. The 1,3-dicarbonyl compound undergoes single-electron oxidation to afford an electrophilic 1,3-dicarbonyl radical under visible light irradiation Due to the polarity of the free radical, the electrophilic radical adds to the electron-rich olefin to afford the nucleophilic radical. It coupled with the heteroarene to afford the three-component coupling products.

A general and mild strategy using semiconductor quantum dots (QDs) as photocatalysts for coupling a broad range of available allylic C(sp3)-H bonds with α-amino C-H bonds or heteroarenes, resp., under sunlight irradiation (> 85 examples) was reported. The protocol bypasses stoichiometric oxidant or reductant and pre-functionalization of both the coupling partners and produces hydrogen (H2) as the byproduct. The outstanding efficiency and selectivity and step- and atom-economy represents the first direct alkylation and arylation of allylic C(sp3)-H bonds with hydrogen evolution powered by solar energy.
