Synthesis method of cinnamyl aldehyde compound

The invention discloses a synthesis method of a cinnamyl aldehyde compound. The cinnamyl aldehyde compound is synthesized through the crossed dehydrogenation coupling reaction with fatty aldehyde andsbstituted sromatic hydrocarbon as the initial raw materials and palladium chloride and amino acid as the catalysts. Compared with a traditional cinnamyl aldehyde compound synthesis method, the methodis simple in operation, mild in reaction condition, low in applied reagent price, high in efficiency and high in atom utilization rate.

Cyclamen aldehyde synthesis: Aldol condensation followed by hydrogenation over ruthenium catalyst

Cyclamen aldehyde is a fragrant substance with the scent of cyclamen or lily-of-the-valley. In this work, the desired cyclamen aldehyde was prepared by twostep synthesis. At the first step, aldol condensation of 4-isopropylbenzaldehyde and propanal was carried out. The influence of used catalyst (potassium hydroxide and sodium methoxide) and propanal amount were tested. Propanal was used in excess and it was added to the reaction mixture dropwise (to prevent its self-condensation to 2-methylpent-2-enal). Resulting mixture of 4-isopropylbenzaldehyde and forcyclamen aldehyde was hydrogenated using different Ru/C catalysts. The products detected in hydrogenation reaction mixture were: desired cyclamen aldehyde, cyclamen alcohol and forcyclamen alcohol. The influence of catalyst type and amount, reaction temperature and hydrogen pressure on the reaction course was tested. The highest yield (19.4 %) was obtained using pressure 10 MPa, temperature 110 °C and 2 wt% of catalyst Ru/C.
