Phenylacetaldehyde is an organic compound used in the synthesis of fragrances and polymers. [1] Phenylacetaldehyde is an aldehyde that consists of acetaldehyde bearing a phenyl substituent; the parent member of the phenylacetaldehyde class of compounds.
[3] [4] In both species, it is subsequently metabolized into 4-hydroxyphenylacetate by aldehyde dehydrogenase (ALDH) enzymes in humans and the phenylacetaldehyde dehydrogenase (feaB) enzyme in E. coli. [3] [4] [5] The condensation of 4-hydroxyphenylacetaldehyde and dopamine is a key step in the biosynthesis of benzylisoquinoline alkaloids.
Styrene oxide is slightly soluble in water. A trace amount of acid in water causes hydrolysis to racemic phenylethyleneglycol via a benzylic cation. If the amount of water is not sufficient, acid-catalyzed isomerization for phenylacetaldehyde will occur. [2]
Phenylacetic acid (conjugate base phenylacetate), also known by various synonyms, is an organic compound containing a phenyl functional group and a carboxylic acid functional group.
In organic chemistry, a cyanohydrin reaction is an organic reaction in which an aldehyde (−CH=O) or ketone (>C=O) reacts with a cyanide anion (N≡C −) or a nitrile (−C≡N) to form a cyanohydrin (>C(OH)C≡N).
[4] [5] The reaction has since been extended to the synthesis of β-keto esters from the condensation between aldehydes and diazo esters. [6] The general reaction scheme is as follows: General Scheme for Buchner Reaction. The reaction yields two possible carbonyl compounds (I and II) along with an epoxide (III). The ratio of the products is ...
DOPAL is known to be a dopaminergic neurotoxin. [2] [4] [3] It is much more potent in this regard than dopamine itself and other metabolites of dopamine.[2] [4] [3] According to the catecholaldehyde hypothesis, DOPAL plays a role in aging-related dopaminergic neurodegeneration and in the pathogenesis of Parkinson's disease.
These compounds are important in the synthesis of heterocyclic compounds. The analogous 1,4-addition of an aldehyde to an enone is called the Stetter reaction . In biochemistry , the coenzyme thiamine is responsible for biosynthesis of acyloin-like compounds utilizing the benzoin addition.
