应用
Ethyl 5-[(4-methylphenyl)sulfonyl]-3-oxopentanoate can be used as a reactant to prepare:
- Ethyl 3-oxopent-4-enoate (Nazarov′s reagent) via base-induced β-elimination reaction. Nazarov′s reagent can be employed as an anulating agent in Robinson annulation of cyclic β-diketones and cycloalkanones.
- γ-pyrones via triflic anhydride-mediated electrophilic condensation reaction.
Reactant for:
- Preparation of the Nazarov reagent via base-induced ß-elimination reaction
