Abstract

As a first non-metal-catalyzed oxidation for the in situ generation of acylnitroso species, we describe the hypoiodite catalysis using tetra-n-butylammonium iodide as precatalyst with tert-butyl hydroperoxide or hydrogen peroxide as a terminal oxidant. This method can be applied to hetero Diels–Alder (HDA) reactions with dienes and ene reactions with alkenes. Furthermore, the conversions of the representative HDA adduct to nitrone and 2-amino alcohols were demonstrated. Compared with previous metal-catalyzed oxidation methods, this work provides a more efficient and environmentally friendly procedure.
