Visible light photocatalysis has recently emerged as a powerful tool expanding the arsenal of bond-forming protocols. Due to its simplicity, economy and environmental friendliness it has received increased attention. 3 Within this research area, the use of carboxylic acids as substrates has become an interesting strategy allowing for the generation of alkyl radicals under mild conditions and opening access to new reaction profiles. Stereoselective processes are challenging and receive special attention. Interestingly, processes involving chiral radical precursors are known in the literature with the memory of chirality phenomenon observed in such processes. Aziridines has recently emerged as a useful group of reactants readily participating in the radical processes resulting in the development new strainrelease bond forming reactions. The chromen-4-one and its C-3-substituted derivatives can be found in various bioactive molecules relevant for the life-science industry (Scheme 1, top). Selected examples of bio-relevant C-3-substituted chromen-4ones are shown in the Scheme 1. Crodimyl possesses muscle relaxant properties and exerts vasodilator effect on coronary blood vessels. Hyperimone B has been reported to exhibit antitumor activity. Iguratimod is an anti-inflammatory small molecule drug used for the treatment of rheumatoid arthritis. Flavoxate was employed as an anticholinergic agent for its antimuscarinic effect. Given our interest in the development of new synthetic methodologies utilizing chromone-3-carboxylic acids as starting materials, it was envisioned that they should be able to participate in the cross-couplings reaction with aziridines leading to C-3substituted chromen-4-ones, thus resulting in the unique C(sp 2 )-C(sp 3 ) bond forming process. Devised reactivity can be considered as a formal alkenylation of aziridines providing access to homoallylic amines. However, at the outset of our studies challenges related to stereospecificity of the process were considered. We questioned whether the stereochemical information of 1 was possible to be preserved under these reaction conditions following memory of chirality phenomenon.
