General Description

Geranic acid is a monoterpenemainly used in flavor, fragrance, cosmetics and agro-industries. In vitro studies show that geranic acid exhibits strong inhibitory activity against Fusarium graminearum and Colletotrichum graminicola, the two main fungal pathogens of maize. It may be responsible for the potent tyrosinase inhibitory activity of lemongrass (Cymbopogon citratus).

Biochem/physiol Actions

Odor (neat): sweet, floral green, geranium leaf-like, woody with a citrus orange body nuance.

Method for synthesizing aromatic folic acid from methyl heptenone

The invention provides a method for synthesizing aromatic folic acid from methyl heptenone. The method comprises the following steps: under the actions of a Lewis acid catalyst and a cocatalyst, condensing methyl heptenone and ketene to obtain a beta-propiolactone intermediate, hydrolyzing beta-propiolactone, acidifying and dehydrating to obtain aromatic folic acid. The synthetic route is novel, alarge amount of methyl heptenone and ketene which are easy to obtain and low in price serve as starting materials, the aromatic folic acid is synthesized through two-step reaction, the synthetic route is short, the yield is high, and the cost advantage is good. Secondly, in hydrolysis and dehydration reactions, strong acid resin is used as a catalyst, mixed liquor of ethanol water and the like isused as a solvent, and a tubular reactor is adopted so that continuous hydrolysis and dehydration of beta-propiolactone are realized, the reaction yield is high, and the use amount of the catalyst issmall.
