Abstract
Abstract An oxo group is introduced at the allylic position of 3-methyl-2-cyclopenten-1-one and β-ionone on treatment with VO(OR)Cl 2 in ROH. VO(OR)Cl 2 induces γ-alkoxylation in the case of 2-cyclopenten-1-one. Reaction of 1-acetyl-1-cyclohexene with VO(OEt)Cl 2 results in γ-alkoxylation and/or aromatization to give 1-acetyl-3-ethoxy-1-cyclohexene and the corresponding aromatic.
