Advanced Synthesis & Catalysis, 360(6), 1262-1266. doi:10.1002/adsc.201700937 | Journal: | Advanced Synthesis & Catalysis | Abstract: | Synthesis of 3,4-pyrroline derivatives via visible-light-induced hydro/oxyimination of unactivated olefins is reported. In the presence of the photoredox catalyst fac-Ir(ppy)3, the key iminyl radical intermediate can be readily generated from O-acyl oximes, and undergoes intramolecular cyclization and H-abstraction from solvent or is trapped by TEMPO to give the corresponding hydro/oxyimination product, respectively. Mechanistic investigations indicate that N,N′-dimethylpropylene urea (DMPU) works as both reducing agent for catalyst regeneration and H-donor for product formation in this process. | URI: | https://hdl.handle.net/10356/139419 | ISSN: | 1615-4150 | DOI: | 10.1002/adsc.201700937 | Rights: | © 2018 Wiley-VCH Verlag GmbH & Co.
