Nitrones and Oxaziridines. XL. Oxidation of 2H-Pyrroles and 3-Benzoyloxy-1-pyrrolines

Abstract

Peracid oxidation of 2H-pyrroles (1a-d) gave the related 2H-pyrrole 1-oxides (2a-d). Similar oxidation of the 3-benzoyloxy-1-pyrroline (7a) also gave a 2H-pyrrole 1-oxide (9), while other benzoyloxy pyrrolines (7b,c) yielded the related oxaziridines (8b,c). Some other oxygenated by-products were also identified.
