Chavicol
Chavicol (''p''-allylphenol) is a natural phenylpropene, a type of organic compound. Its chemical structure consists of a benzene ring substituted with a hydroxy group and a propenyl group. It is a colorless liquid found together with terpenes in betel oil. Properties and reactions Chavicol is miscible with alcohol, ether, and chloroform. Dimerization of chavicol gives the neo-lignan magnolol. Uses Chavicol is used as an odorant in perfumery and as a flavor. It is found in many essential oils, including anise and gardenia. Biosynthesis Chavicol is formed in sweet basil (''Ocimum Basilicum'') by the phenylpropanoid pathway via ''p''-coumaryl alcohol. The allylic alcohol in ''p''-coumaryl alcohol is converted into a leaving group. This then leaves thus forming a cation, this cation can be regarded as a quinone methide which then is reduced by NADPH to form either anol or chavicol. : See also * Estragole, the methyl ether * Safrole Safrole is an organic compound with the ...

Allyl Compounds
In organic chemistry, an allyl group is a substituent with the structural formula . It consists of a methylene bridge () attached to a vinyl group (). The name is derived from the scientific name for garlic, . In 1844, Theodor Wertheim isolated an allyl derivative from garlic oil and named it "". The term allyl applies to many compounds related to , some of which are of practical or of everyday importance, for example, allyl chloride. Allylation is any chemical reaction that adds an allyl group to a Substrate (chemistry), substrate. Nomenclature A site adjacent to the unsaturated carbon atom is called the allylic position or allylic site. A group attached at this site is sometimes described as allylic. Thus, "has an allylic hydroxyl group". Allylic Carbon–hydrogen bond, C−H bonds are about 15% weaker than the C−H bonds in ordinary Orbital hybridisation, sp3 carbon centers and are thus more reactive. Benzylic and allylic are related in terms of structure, bond strength ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Biosynthesis Of Chavicol
Biosynthesis, i.e., chemical synthesis occurring in biological contexts, is a term most often referring to multi-step, enzyme- catalyzed processes where chemical substances absorbed as nutrients (or previously converted through biosynthesis) serve as enzyme substrates, with conversion by the living organism either into simpler or more complex products. Examples of biosynthetic pathways include those for the production of amino acids, lipid membrane components, and nucleotides, but also for the production of all classes of biological macromolecules, and of acetyl-coenzyme A, adenosine triphosphate, nicotinamide adenine dinucleotide and other key intermediate and transactional molecules needed for metabolism. Thus, in biosynthesis, any of an array of compounds, from simple to complex, are converted into other compounds, and so it includes both the catabolism and anabolism (building up and breaking down) of complex molecules (including macromolecules). Biosynthetic processes are ofte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anol
Anol, also known as ''p''-hydroxypropenylbenzene, is a simple phenol that was derived via demethylation from anethole, an estrogenic constituent of anise and fennel, by Sir Charles Dodds in 1937. It was reported to possess extremely potent estrogenic activity on par with that of steroidal estrogens like estrone, with a dose of 1 μg inducing estrus The estrous cycle (, originally ) is a set of recurring physiological changes induced by reproductive hormones in females of mammalian subclass Theria. Estrous cycles start after sexual maturity in females and are interrupted by anestrous phas ... in rats. However, subsequent studies with different preparations of anol failed to confirm these findings, and it was found that dimerization of anol into dianol and hexestrol can rapidly occur and that the latter impurity was responsible for the highly potent estrogenic effects. Dodds later synthesized the structurally related and extremely potent estrogen diethylstilbest ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
