Application

Ethyl 2-chloro-2-(hydroxyimino)acetate has been used:
  • in the preparation of (+)-and (−)-Δ2-isoxazolines
  • in the synthesis of CIP-AS (−), a chiral amino acid structurally related to glutamic acid, potential agonist at the ionotropic (±±)-2-amino-3-(3-hydroxy-5-methylisoxazol-4-yl)propionic acid (AMPA)-kainate receptors
  • to generate ethoxycarbonylformonitrile oxide, in situ by treatment with sodium bicarbonate
  • to prepare N-azirdinyloximes which on treatment with scandium triflate (418218) provide dihydro-oxadiazines
