Redox activated amines in the organophotoinduced alkylation of coumarins?
Organic & Biomolecular Chemistry Pub Date: 2022-07-07 DOI: 10.1039/D2OB00943A
Abstract
The coumarin core represents the quintessential scaffold of many natural products. While C-3 alkylation is easily achievable, effective greener strategies for C-4 alkylation have been less forthcoming. Herein, we report a metal-free photoinduced deaminative strategy for C-4 alkylation of coumarins using redox activated secondary and benzylic amine derived Katritzky pyridinium salts.
