An unprecedented approach to isoxazoline aldoximes via the reactions of nitromethane and olefins is achieved. Nitromethane is electrochemically activated to serve as both the heterocyclic skeleton and oxime sources for the construction of isoxazoline aldoximes.

The homoallyl moiety, (h)Allyl, is presented as a general protecting group for several functionalities. It can be chemoselectively removed via a sequential, one-pot cross-metathesis/elimination sequence.

Allylic and benzylic alcohols can be selectively oxidized to their corresponding aldehydes or ketones in water containing nanoreactors composed of the designer surfactant TPGS-750-M. The oxidation relies on catalytic amounts of CuBr, bpy, and TEMPO, with N-methyl-imidazole; air is the stoichiometric oxidant.
