Synonyms. group are primary alcohols, aldehydes, or carboxylic acids, or their corresponding esters and acetals. The primary oxygenated functional group is located on a three-carbonsaturated or unsaturated (i.e~, at the 2,3 position) chain with a benzene ring at the 3 position (i.e., a 3-phenylpropyl or 3-phenyl-2-propenylgroup). The role of graphitic nitrogen and the presence of π-conjugated functional groups are demonstrated using the state-of-the-art density functional theory calculations.

The end functional groups can be changed using different aromatically substituted cinnamyl alcohol derivatives. Different monomers were investigated and the presence of the functional groups was shown by NMR spectroscopy and MALDI-ToF mass spectrometry. N can be reduced to -CH=NH (normal addition gives -CH 2 NH 2) and cinnamaldehyde to cinnamyl alcohol (normal addition gives hydrocinnamyl alcohol). Selective reduction of functional groups can also be achieved by chemical modification of the reagent, e.g. as LiAlH(OBu t ) 3 , or by the use of the related complex hydrides, lithium and sodium Therefore, cinnamyl alcohol is reduced to the dihydro compound by Raney nickel in ethanol at 20 o C and 1,2-dimethyl-cyclohexane by hydrogen and platinum oxide in acetic acid is transformed mostly to cis-1,2-dimethylcyclohexane.

Cinnamyl alcohol is naturally occurrent only in small amount, so its indus Lignin is a macromolecule formed by the polymerisation of three phenylpropane monomers (C9 units), the p-hydroxy-cinnamyl alcohols, which differ in the degree of methoxyl substitution in C3 and C5: p-coumaryl alcohol, coniferyl alcohol and sinapyl alcohol (Fig. 3.9).

"Functional characterization of cinnamyl alcohol dehydrogenase during developmental stages and under various stress conditions in kenaf (Hibiscus cannabinus L.)," BioRes. 11(1), 105-125. Abstract In this study, the entire gene encoding cinnamyl alcohol dehydrogenase in kenaf ( HcCAD2 ) was cloned and characterized. gamma-PHENYLALLYL ALCOHOL, ZIMTALCOHOL: Chemical Names: CINNAMYL ALCOHOL: JECFA number: 647: COE number: 65: FEMA number: 2294: Functional Class: Flavouring Agent.

Sinapyl alcohol is a primary alcohol, being cinnamyl alcohol hydroxylated at C-4 and methoxylated at C-3 and -5.

It forms a white crystalline solid when pure, or a yellow oil when even slightly impure. It can be produced by the hydrolysis of storax. Cinnamyl alcohol has a distinctive odour described as "sweet, balsam, hyacinth, spicy, green, powdery, cinnamic" and is used in perfumery and as a deodorant.

FLAVOURING_AGENT Title: Epoxidation of trans-Cinnamyl Alcohol1 Introduction: Epoxidation of alkenes leads to a useful three-membered-ring ether (an epoxide) that is reactive toward nucleophiles. Nucleophilic attack on epoxides gives a ring-opened product that possesses two functional groups located on adjacent carbon atoms.

IFRA. International memory function; these are released into the blood circulation. Some fragrance substances, e.g. cinnamal and cinnamyl alcohol, as well as MP may.
The three classes differ in pat-terns of evolution and expression, implying that functional divergence has occurred among them. Our study also Cinnamyl alcohol is a naturally occurring compound that is found within cinnamon.
