Ethyl diazoacetoacetate Chemical Properties, Uses, Production

Uses

Ethyl diazoacetoacetate can be used as a reactant to synthesize:

  • 1,4-oxathiocines and thiopyran derivatives via Rh-catalyzed reaction with 2-amino-4,5-dihydro-3-thiophenecarbonitriles.
  • β-keto esters via C-H insertion reaction with aromatic aldehydes using NbCl5 as a catalyst.
  • Diazoacetoacetate derivatives by reacting with aldehydes via aldol condensation and subsequent and in situ oxidation reaction.
  • Isoquinolone and pyridone derivatives by Rh-catalyzed C-H activation/annulation reaction with various N-methoxybenzamides.
