Sustainable catalytic protocols for the solvent free epoxidation and: Anti -dihydroxylation of the alkene bonds of biorenewable terpene feedstocks using H2O2 as oxidant

A tungsten-based polyoxometalate catalyst employing aqueous H2O2 as a benign oxidant has been used for the solvent free catalytic epoxidation of the trisubstituted alkene bonds of a wide range of biorenewable terpene substrates. This epoxidation protocol has been scaled up to produce limonene oxide, 3-carene oxide and α-pinene oxide on a multigram scale, with the catalyst being recycled three times to produce 3-carene oxide. Epoxidation of the less reactive disubstituted alkene bonds of terpene substrates could be achieved by carrying out catalytic epoxidation reactions at 50 °C. Methods have been developed that enable direct epoxidation of untreated crude sulfate turpentine to afford 3-carene oxide, α-pinene oxide and β-pinene oxide. Treatment of crude epoxide products (no work-up) with a heterogeneous acid catalyst (Amberlyst-15) results in clean epoxide hydrolysis to afford their corresponding terpene-anti-diols in good yields.

Ionones and &β-Ionylideneacetic Acids: Their Influence on Abscisic Acid Biosynthesis by Cercospora rosicola

Several ionones and β-ionylideneacetic acids inhibited absicisic acid (ABA) biosynthesis in Cercospora rosicola at 100 μM.At lower concentrations, α-ionone, 1',2'-dihydroxy-1',2'-dihydro-β-ionone and 4'-keto-α-ionone enhanced ABA biosynthesis.Conversions

Synthesis and Chirality of the Enantiomeric 6-Hydroxy-α-ionones and of cis- and trans-5,6-Dihydroxy-5,6-dihydro-β-ionones

We describe the synthesis of (-)-(5R,6S)-5,6-dihydroxy-5,6-dihydro-β-ionone (10) and (+)-(5S,6S)-5,6-dihydroxy-5,6-dihydro-β-ionone (12).The absolute configuration of these compounds has been established by correlation with (R)-4-hydroxy-β-ionone (1).
