Synthesis method of alpha-cyclocitral

The invention discloses a synthesis method of alpha-cyclocitral. The method comprises the steps of (1) carrying out Diels-Alder reaction on 1,3-pentadiene and methylcrotonaldehyde under the catalysisof lewis acid to obtain a 2,6,6-trimethyl-3-cyclohexenyl formaldehyde crude product; (2) carrying out isomerization reaction on the 2,6,6-trimethyl-3-cyclohexenyl formaldehyde crude product obtained in step (1) under the catalysis of a catalyzer to generate an alpha-cyclocitral crude product. The method provided by the invention is easy to get reaction raw materials, mild in conditions, easy to control, free of generating byproducts, simple in process, favorable in industrial production, green and environmentally friendly.

Synthesis of three putative kairomones of the beech leaf-mining weevil Orchestes fagi (L.)

The beech leaf-mining weevil, Orchestes fagi (L.), also known as the beech flea weevil, is a common and widespread pest of beech, Fagus sylvatica L., in its native Europe. It now appears to be well established in Nova Scotia, Canada. We report a novel synthesis of 9-geranyl-p-cymene and syntheses of 9-geranyl-α-terpinene and 1,1-dimethyl-3-methylene-2-vinylcyclohexane, making partial use of known methods. All three of these compounds are found in beech leaf volatiles and/or wood and are putative kairomones of the beech leaf-mining weevil.

Improved synthesis of methyl 3-oxo-2,6,6-trimethylcyclohex-1-ene-1- carboxylate, an A-ring intermediate for (±)strigol

Methyl 3-oxo-2,6,6-trimethylcyclohex-1-ene-1-carboxylate was synthesised over eight steps from the starting material of citral instead of α-ionone. KMnO4, HC(OEt)3 and O2/TEMPO/CuCl were substituted for NaIO4, CH3I and pyridinium chlorochromate, respectively. Every step was simplified and gave a 48% overall yield. The procedure is suitable for large scale production.
