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.
