In recent years, amination of alkylboronates through ionic copper catalysis or boron-ate complex 1,2-metalation has been well established, but complementary radical processes remain less studied before. Herein, based on rational design, we develop several imine-type N-centered scavengers and apply them to the alkylboronates. The reaction proceeds under mild photoredox-catalyzed transition-metal-free conditions features excellent functional group tolerance. It also enables preparation a range medicinally valuable amine derivatives from natural products. Further application this reagent in C-H amination, deoxygenative decarboxylative three component trifluoromethylative/sulfonylative aminations are realized. mechanistic studies DFT calculations conducted provide detailed evidence for mechanism.

Abstract BACKGROUND The development of fungicides with low cross resistance, high efficacy and resistance plays a central role in protecting crops, reducing yield losses, improving quality maintaining global food security. Based on this important role, after systematic optimization strategy, novel heterocyclic amide derivatives bearing diphenylmethyl fragment were screened, synthesized verified the spectrographic x‐ray diffraction analysis. RESULTS In study, aforementioned obtained compound B19 that was measured for antifungal activity against Rhizoctonia solani (median effective concentration, EC 50 = 1.11 μg mL −1 ). Meanwhile, anti‐ R. protective effect (79.34%) evaluated vivo at 100 , which is comparable to control agent fluxapyroxad (80.67%). Thence, morphological observations revealed induced mycelium disruption shrinking, mitochondrial number reduction apoptosis acceleration, consistent results membrane potential cell permeability. Further investigations found target enzyme SDH, exerted fluorescence quenching dynamic curves similar commercialized SDHI fluxapyroxad. Additionally, research by molecular docking MD simulations demonstrated had binding mode acting surrounding residues SDH active pocket offluxapyroxad.
