Application

Diethyl oxalacetate sodium salt can be used as a reagent to synthesize:
  • Spiro[indoline-3,4′-pyrano[2,3-c]pyrazole derivatives via a one-pot reaction with isatins, malononitrile, and hydrazine hydrate.
  • 2,3-dioxo-4-carboxy-5-substituted pyrrolidines by reacting with various aldehydes and primary amines.
  • 2-nitro-4-fluoro triazole diester by treating with 2-nitro-4-fluoro-phenylazide.
