Novel approach to the ring-opening of 4-isoxazolines: One-pot synthesis of α,β-enones
摘要:
Treatment of 4-isoxazoline derivatives with methyl iodide affords alpha-beta-enones in excellent yields. The novel rearrangement pathway, proceeding through an intermediate isoxazolinium salt, is interpretable on the basis of the base removal of the hydrogen atom at N-CH3 group.
