REFERENCES

• The dimetallated species (n-BuLi, -78^o) can be alkylated at the ɑ-position: Tetrahedron Lett., 25, 263 (1984).
• Nitrile oxides can be generated from other aldoximes in a similar manner. The resulting isoxazolines can readily be reduced to 3-hydroxy ketones.
• Chlorination with NCS: Tetrahedron, 40, 2985 (1984), or chlorine, gives the chloroxime, dehydrochlorination of which generates acetonitrile N-oxide, a reactive 1,3-dipole which undergoes cycloadditions with alkenes providing a one-pot route to 2-isoxazolines (same ref.):
