3-Methyl-2-cyclohexen-1-one Chemical Properties,Uses,Production
Description
May be prepared by acid hydrolysis and decarboxylation of the corresponding 4-carbetoxy derivative; by oxidation of 1-methylcyclohex-l-ene with chromium trioxide in acetic acid; by cyclization of 3-carbetoxy-6-chlorohept-5-en-2-one with sulfuric acid.
Chemical Properties
3-Methyl-2-cyclohexen-1-one is a nonaromatic cyclic ketone with a medicinal, phenolic, mild cherry aroma
Chemical Properties
CLEAR VERY SLIGHTLY YELLOW TO BROWN LIQUID
Occurrence
Reported found in oil of Mentha pulegium, cocoa, coffee, filbert, sweet corn, dried bonito, katsuobushi, wild rice and clam. Also produced by some animals in vivo
Uses
3-Methyl-2-cyclohexen-1-one was used in the synthesis of 19-nor-1α, 25-dihydroxyvitamin D(3) derivatives. It was also used in sex pheromone of the Douglas-fir beetle. Used in nut flavor.
Uses
3-Methyl-2-cyclohexenone is an insect sex pheromone of the Douglas-fir beetle. It can be used as a starting material:
- In the total synthesis of ()-ar-tenuifolene, a naturally occurring aromatic sesquiterpene.
- To synthesize an organic building block 2-trimethylsilyl-3-methyl-cyclohexenone.
- In the total synthesis of natural diterpenoids (+)-taiwaniaquinone H and (+)-dichroanone.
Definition
ChEBI: 3-Methyl-2-cyclohexen-1-one is a cyclic olefin.
Preparation
By acid hydrolysis and decarboxylation of the corresponding 4-carbetoxy derivative; by oxidation of 1-methylcyclohex-1-ene with chromium trioxide in acetic acid; by cyclization of 3-carbetoxy-6-chlorohept-5-en-2-one with sulfuric acid.
Aroma threshold values
Aroma characteristics at 2.0%: sweet, nutty, phenolic, walnut, fruity, almond and benzoin
Taste threshold values
Taste characteristics at 50 ppm: nutty, musty, phenolic and woody with grain-like nuances.
