Isomerization of eugenol to isoeugenol

Reaction Kinetics and Catalysis Letters, 1987
The isomerization of eugenol to isoeugenol was investigated by employing catalysis by KOH in amyl alcohol or glycerol, or by RhCl3. A number of factors which affect the reaction (solvent, temperature, molar ratios, presence of water) were examined.

Deodorants: an experimental provocation study with isoeugenol

Contact Dermatitis, 2005
Axillary dermatitis is common and overrepresented in people with contact allergy to fragrances. Many people suspect their deodorants to be the incriminating products. In order to investigate the significance of isoeugenol in deodorants for the development of axillary dermatitis when used by people with and without contact allergy to isoeugenol, patch ...

Isoeugenol: A survey of consumer patch-test sensitization

Food and Chemical Toxicology, 1983
The potential of isoeugenol, an important fragrance and flavour ingredient, to induce delayed contact hypersensitivity or to elicit pre-existing sensitization reactions in man was evaluated by analysing patch-test data from dermatitic and non-dermatitic subjects.

Oxidation of isoeugenol by Nocardia iowensis

Enzyme and Microbial Technology, 2008
Abstract Isoeugenol is a starting material for both the synthetic and biotechnological production of vanillin and vanillic acid. Nocardia iowensis DSM 45197 (formerly Nocardia species NRRL 5646) resting cells catalyze the conversion of isoeugenol to vanillic acid, vanillin, vanillyl alcohol and guaiacol.

Studies on the Photodimerization of Isoeugenol

Journal of the Chinese Chemical Society, 1978
AbstractUnder the irradiation of the ultraviolet light, Isoeugenol (I) undergoes dimerization in acetone to give diisoeugenol (II) and dehydrodiisoeugenol (III). The structures are determined by the comparison of the mixed m. p., I. R. spectra and T. L. C. with synthesized authentic samples. Also the photoreaction mechanism is discussed in detail.

Isoeugenol's biotransformation to vanillin using microorganisms

American Journal of Chemistry
The biotechnological route of producing natural biological food products is preferred over synthetically created ones. One such pathway is biotransformation, which entails the chemical transformation of one substance into another using microorganisms acting as biocatalysts.
