Copper-catalyzed cross-dehydrogenative coupling of pyridine N-oxides with cyclic ethers

Journal of Organometallic Chemistry, 2016
Highly chemo- and regioselective synthesis of 2-alkylpyridine N-oxides from pyridine N-oxides and cyclic ethers has been developed through copper-catalyzed CDC reactions using CuO as the catalyst under mild reaction conditions. Optimization study showed that, K2S2O8 is the best oxidant for the reaction and the mechanistic study proved the radical ...

NMR spectra of cyclic nitrones. 4. Synthesis and 13C NMR spectra of 4H-imidazole N-oxides and N,N-dioxides

Chemistry of Heterocyclic Compounds, 1988
4H-Imidazole 1,3-dioxides and 4H-imidazole 3-oxides were obtained by oxidation of 1-hydroxy-3-imidazoline 3-oxides and 1-hydroxy-3-imidazolines with lead and manganese dioxides or the stable nitroxyl radical, while 4H-imidazole 1-oxides were obtained by thermal decomposition of 1-acetoxy-3-imidazoline 3-oxides.

Enantioselective Addition of Cyclic Enol Silyl Ethers to 2‐Alkenoyl‐Pyridine‐N‐Oxides Catalysed by Cu^II–Bis(oxazoline) Complexes

Chemistry – A European Journal, 2012
AbstractAsymmetric reactions involving (E)‐3‐aryl‐1‐(pyridin‐2‐yl‐N‐oxide)prop‐2‐en‐1‐ones and cyclic enol silyl ethers show good yields and excellent enantioselectivities (up to 99.9 % ee) when catalysed by bis(oxazoline)–CuII complexes. Different reaction pathways can be followed by different enol silyl ethers: with 2‐(trimethylsilyloxy)furan, a ...
