J Am Chem Soc. 2018 Jan 31;140(4):1243-1246. doi: 10.1021/jacs.7b12864. Epub 2018 Jan 22.

Abstract

This report details a new method for site-selective methylene oxidation adjacent to azaheterocycles. A dual catalysis approach, utilizing both an iron Lewis acid and an organic hydroxylamine catalyst, proved highly effective. We demonstrate that this method provides complementary selectivity to other known catalytic approaches and represents an improvement over current heterocycle-selective reactions that rely on stoichiometric activation.
