Application of a Dual Catalytic Nickel/Iridium-Based Photoredox Reaction to Synthesize 2-Alkyl-N-Arylindoles in a Continuous Flow

N,N'-Diaryldihydrophenazines as Visible-Light Photocatalysts for Anilines' Arylation Using a Dual Photoredox/Ni(II) Cross-Coupling Strategy

It has been shown that cheap and easily available N,N'-diaryldihydrophenazines can successfully replace Ir(III)- and Ru(II)-based photocatalysts in the dual photoredox/Ni(II) C-N coupling of aryl halides with a wide range of anilines (32 examples). The efficient, operationally simple approach to diarylamines has been elaborated, which is amenable to scaling up via a flow apparatus.

Photocatalysis in the Life Science Industry

In the pursuit of new pharmaceuticals and agrochemicals, chemists in the life science industry require access to mild and robust synthetic methodologies to systematically modify chemical structures, explore novel chemical space, and enable efficient synthesis. In this context, photocatalysis has emerged as a powerful technology for the synthesis of complex and often highly functionalized molecules. This Review aims to summarize the published contributions to the field from the life science industry, including research from industrial-academic partnerships. An overview of the synthetic methodologies developed and strategic applications in chemical synthesis, including peptide functionalization, isotope labeling, and both DNA-encoded and traditional library synthesis, is provided, along with a summary of the state-of-the-art in photoreactor technology and the effective upscaling of photocatalytic reactions.
