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

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 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
