Photoredox Catalysis in Organic Chemistry
In recent years, photoredox catalysis has come to the forefront in organic chemistry as a powerful strategy for the activation of small molecules. In a general sense, these approaches rely on the ability of metal complexes and organic dyes to convert visible light into chemical energy by engaging in single-electron transfer with organic substrates, thereby generating reactive intermediates. In ...
متن کاملPrebiotic synthesis of simple sugars by photoredox systems chemistry.
A recent synthesis of activated pyrimidine ribonucleotides under prebiotically plausible conditions relied on mixed oxygenous and nitrogenous systems chemistry. As it stands, this synthesis provides support for the involvement of RNA in the origin of life, but such support would be considerably strengthened if the sugar building blocks for the synthesis--glycolaldehyde and glyceraldehyde--could...
متن کاملChemoselective Radical Dehalogenation and C-C Bond Formation on Aryl Halide Substrates Using Organic Photoredox Catalysts.
Despite the number of methods available for dehalogenation and carbon-carbon bond formation using aryl halides, strategies that provide chemoselectivity for systems bearing multiple carbon-halogen bonds are still needed. Herein, we report the ability to tune the reduction potential of metal-free phenothiazine-based photoredox catalysts and demonstrate the application of these catalysts for chem...
متن کاملFormal intramolecular photoredox chemistry of anthraquinones in aqueous solution: photodeprotection for alcohols, aldehydes and ketones.
The formal intramolecular photoredox reaction initially discovered for the parent 2-(hydroxymethyl)anthraquinone (1) in aqueous solution has been extended to a variety of anthraquinones derivatives 6-13, to explore the generality of the reaction, and to investigate its potential utility as a photodeprotecting chromophore. In addition, the related diketone 14 was studied to investigate the need ...
متن کاملSynthesis of Aldehydic Ribonucleotide and Amino Acid Precursors by Photoredox Chemistry**
The photoredox cycle oxidizes 1 to cyanogen 2 and generates associated reducing power in the form of protons and hydrated electrons, which reduce further 1 to formaldehyde imine 3. Hydrolysis of 3 to formaldehyde 4 is then followed by addition of 1 to give glycolonitrile 5. Iteration of this process results in the sequential production of glycolaldehyde 6, its cyanohydrin 7, and glyceraldehyde ...
