A Novel Reactivity of α-Nitro Ketone Tosylhydrazones with DBU. Synthesis of α,β-Unsaturated Enone Tosylhydrazones.

Treatment of α-nitro ketone tosylhydrazones with DBU gives 1,4-elimination of nitrous acid affording 1-tosylazoalkenes which, under basic conditions (DBU), tautomerize to the more stable enone tosylhydrazones.The obtained tosylhydrazones may be used as st

A NEW ROUTE TO 1,4-DIKETONES AND ITS APPLICATION TO (Z)-JASMONE AND DIHYDROJASMONE SYNTHESIS.

(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.
