The Uses of 2-CHLORO-2-HYDROXYIMINOACETIC ACID ETHYL ESTER
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
