Photoredox catalysis, Organocatalysis, C-H Functionalization, Heterocycles, Late-stage functionalizationIn the last decade, visible light photoredox catalysis promoting radical‐based organic transformations has received enormous synthetic applicability, as they allow unfolding of site﹕elective reactivities under ...
Oxidative three-component reactions for the direct synthesis of alpha-amino amides and imides from tertiary amines have been developed. These reactions involve the functionalization of C(sp(3))-H bonds adjacent to nitrogen atoms via mild aerobic oxidation using visible light photoredox catalysis. The...
The one-pot sulfonylation/aminoalkylation of styrene derivatives furnishing substituted γ-sulfonylamines was accomplished through a photoredox-catalyzed four-component reaction. Besides one molecule of water and the sodium counterion of the sulfinate, all atoms of the starting materials are transferred to...

Herein, we report the organophotoredox-catalyzed semipinacol rearrangement via radical-polar crossover (RPC). A phenothiazine-based organophotoredox catalyst facilitates the generation of an α-hydroxy non-benzylic alkyl radical followed by oxidation to the corresponding carbocation, which can be exploited...
A metal-free visible light photoredox-catalyzed synthesis of N-unsubstituted enaminosulfones from vinyl azides and sodium sulfinates in moderate to high yields is described. The reaction proceeds in ethanol and uses eosin Y as a readily available photocatalyst in combination with nitrobenzene as an...
