A new synthesis of methyl 3-oxo-2-pentyl-1-cyclopentene-1-acetate

The 92:8 equilibrium mixture of (±)-trans-methyl dihydrojasmonate (1) and its cis-isomer is transformed in 63% overall yield into the title compound 4 by epoxidation of the derived enol acetate 2 with peracetic acid/Na2CO3 in toluene and heating the resulting α-acetoxy epoxide 3 in MeOH in the presence of catalytic amounts of methanesulfonic acid.

ELECTROREDUCTIVE INTRAMOLECULAR COUPLING OF γ- AND δ-CYANOKETONES

Electroreduction of γ- and δ-cyanoketones in i-PrOH gave cyclized products α-hydroxyketones and their dehydroxylated ketones, and this reaction was applied to the synthesis of dihydrojasmone, methyl dihydrojasmonate, and Rosaprostol.
