Application

Ethyl benzoylacetate was sed in the preparation of:
  • triazipinones[1]
  • ethyl 2-fluoro-2-benzolyacetate[2]
  • 1,2,4-triazolo[1,5-a]pyrimidine antibiotic essramycin[3]
  • benzo[c]furan-4,7-diones[4]
  • iodonium ylides[5]

General description

Ethyl benzoylacetate is an ester. It undergoes microbial reduction by bakers′ yeast (Saccharomyces cerevisiae), Beauveria sulfurescens or Geotrichum candidum to afford ethyl (S)-3-hydroxy-3-phenylpropionate.[6] It undergoes Claisen condensation reaction with malononitrile to afford 2-cyano-5-phenyl-3,5-dioxopentanonitrile which on cyclization followed by coupling with diazonium salts yields azo derivatives.[7]

A manganese(III)-mediated reaction between 2-benzoyl-1,4-benzoquinones and 1,3-dicarbonyl compounds that produces benzo[c]furan-4,7-diones and anthracene-1,4-diones with high chemoselectivity is described. With ethyl butyrylacetate, by changing the solvent, benzo[c]furan-4,7-diones and anthracene-1,4-diones can be generated in high chemoselectivities. With ethyl benzoylacetate, N ,N-dimethyl acetoacetamide

A short synthesis of the 1,2,4-triazolo[1,5-a]pyrimidine antibiotic essramycin is described involving condensation of aminoguanidine with ethyl benzoylacetate to give an amino-1,2,4-triazole, followed by condensation with ethyl acetoacetate to form the pyrimidone ring.

A number of interesting heterocycles were prepared through interaction of the intermediate 3-amino-8-hydroxy-4-imino-6-methyl-5-phenyl-4,5-dihydro-3H-chromeno-[2,3-d]pyrimidine (1) and reagents such as hydrazonyl halides 2 to furnish triazine derivatives 4a-l. Reaction of 1 with phenacyl bromide afforded compound 5. Moreover, the title compound 1

A simple, practical, and convenient fluorination of 1,3-dicarbonyl compounds was achieved by direct use of aqueous hydrofluoric acid and iodosylbenzene (PhIO). The reaction of ethyl benzoylacetate with the reagent system of aqueous HF and PhIO in CH(2)Cl(2) gave ethyl 2-fluoro-2-benzolyacetate
