, (2019)
Heterocyclic products have been accomplished using microwave-assisted [Pd]-catalyzed intramolecular reductive Heck coupling. The protocol found suitable in delivering indolines, oxindoles, and dihydrobenzofurans. Notably, the process was successful in sol

Hydroarylation of alkenes has been demonstrated to be an atom-economic approach to access functionalized arenes from easily accessible raw materials. Herein, we report a visible light-induced photocatalytic system that enables intramolecular hydroarylation of N-arylacrylamides with high 5-exo-trig selectivity through robust proton-coupled electron transfer (PCET). This mild hydroarylation protocol provides a straightforward entry to structurally valuable oxindoles and complements previously established 6-endo-trig cyclization by photochemical triplet energy transfer (TET).
DMF-Promoted Redox-Neutral Ni-Catalyzed Intramolecular Hydroarylation of Alkene with Simple Arene

A redox-neutral Ni-catalyzed intramolecular hydroarylation of alkene with simple arene has been developed, in which DMF played a proton shuttle role in facilitating the intramolecular coupling, avoiding the use of additional reductants and oxidants. A series of oxindoles with a quaternary center were obtained in up to 99% yield.

We report a new catalyst design for N-heterocycle synthesis that utilizes an alkene-tethered amide moiety as a directing group for aromatic C-H activation. This tethering directing group strategy is demonstrated in a ruthenium-catalyzed intramolecular alk
