Description

General description

3-Ethoxy-2-cyclopentenone (3-Ethoxy-2-cyclopenten-1-one, 3-Ethoxycyclopentenone) is a cyclic β-alkoxy α,β-unsaturated ketone. Its manganese(III) acetate based tandem oxidation has been investigated. Its various physical properties such as density, refractive index and boiling point have been reported.

Application

3-Ethoxy-2-cyclopentenone (3-Ethoxy-2-cyclopenten-1-one) may be used as a starting material in the synthesis of the following:
• allylic cyclopentenyl alcohols like 2-cyclopentenol, 3-methyl-2-cyclopentenol and 3-methoxymethaoxymethyl-2-cyclopentenol
• 3-aminocyclopent-2-en-1-one
• (E)-5-(((2S*,3S*)-3-((benzyloxy)methyl)oxiran-2- yl)methylene)-3-ethoxycyclopent-2-enone, an γ,δ -epoxy-α,β-unsaturated cyclic enone
