(Z)-Jasmone, dihydrojasmone and other 3-methylcyclopent-2-en-1-ones are easily synthetized starting from aldehydes and 1-(2-methyl-1,3-dioxolane-2-yl)-2-nitroethane as reagent for 3-ketobutyl anion synthon.Nitro-aldol condensation is the chainleghtening reaction followed by oxidation and denitration via p-toluenesulfonylhydrazones of the corresponding α-nitroketones.Removal of protecting groups gives 1,4-diketones which are then cyclized with alkali.
