Vanillylidenacetone Usage And Synthesis

Description

Dehydrozingerone (1080-12-2) is a structural half analog of curcumin (Cat.# 10-1243) and is isolated from ginger rhizomes. Dehydrozingerone displays antioxidant, antibacterial and antifungal properties.1 It has also been shown to possess various antitumor effects2,3 and inhibit growth factor/peroxide-stimulated vascular smooth muscle function4.

Chemical Properties

Vanillylidene acetone has a very sweet, warm and tenacious odor.

Physical properties

Yellowish, needlelike crystals. Slightly soluble in water, soluble in alcohol and oils.

Uses

Vanillylidenacetone is one of ferulic acid derivatives. Studies have shown that vanillyl acetone has a certain inhibitory effect on Amaranthus, barnyardgrass, matang, dogwood and rape, among which the best inhibitory effect is on rape and Amaranthus.

Definition

ChEBI: Dehydrozingerone is a hydroxycinnamic acid.

Taste threshold values

Taste characteristics at 200 ppm: balsamic vanilla, with sweet aromatic spicy nuances.

Synthesis

General method: 20% (w/v) aqueous NaOH solution was slowly added to an ethanol solution of vanillin (6a1-d1,6e,6f) and acetone (10-25 eq., excess) at 0-5 °C. The reaction mixture was stirred at room temperature and the progress of the reaction was monitored by thin layer chromatography (TLC). When the vanillin was completely consumed, the excess acetone was evaporated under reduced pressure; subsequently, cold water was added and the resulting mixture was acidified with 3M HCl solution to pH < 7. The precipitated solid product was collected by filtration, washed with cold water and dried under vacuum. The crude product can be purified by column chromatography or recrystallized from a suitable solvent system to afford the target compound 4-(4-hydroxy-3-methoxyphenyl)but-3-en-2-one (7a1-d1,7e and 7f).
