Abstract A visible-light-mediated photocatalytic umpolung synthesis of 1,3-diamines from in situ-generated imines and dehydroalanine derivatives is described. Pivoting on a key nucleophilic addition of photocatalytically generated α-amino radicals to...
Abstract The sulfoximine group has been reported as a versatile and beneficial functionality for pharmaceutical or agrochemical entities. Herein, we report the Csp2–H sulfoximidation of electron-rich arenes under the irradiation of blue light using an organic...
Abstract The selective functionalization of C(sp3)−H bonds at distal positions to functional groups is a challenging task in synthetic chemistry. Reported here is a photoinduced radical cascade strategy for the divergent functionalization of amides and protected...
Abstract A radical deoxychlorination of cesium oxalates has been developed for the preparation of hindered secondary and tertiary alkyl chlorides. The reaction tolerates a number of functional groups, including ketones, alcohols, and amides, and provides complementary...
Abstract The robust CoI precatalyst [CpCo(P{OEt}3)(trans‐MeO2CHC=CHCO2Me)] was investigated in cyclotrimerizations, furnishing benzenes and pyridines from triynes, diynes and nitriles, comparing the influence of different ways of energy supply; namely, irradiation and...
Abstract We report herein the facile and one‐pot synthesis of α‐mono‐ and di‐substituted benzylamines from cheap and readily available α‐amino acids, via photocatalytic decarboxylative arylation in flow. This enables to access intermediates and building blocks that...
