Eugenol and its methyl ether in the synthesis of 3-methyl derivatives of 3,4-dihydroisoquinoline

Russian Journal of Organic Chemistry, 2011
3-Methyl derivatives of 1-substituted 3,4-dihydroisoquinoline were obtained proceeding from eugenol and its methyl ether. The propylene oxide in a three-component reaction with veratrol and ethyl cycnoacetate provided the reaction products in a low yield. The isoeugenol in a linear synthesis also gives a low yield of the target compounds.

Action of eugenol as a retarder against polymerization of methyl methacrylate by benzoyl peroxide

Biomaterials, 1997
This study was undertaken to examine an effect of eugenol on polymerization of methyl methacrylate (MMA) by benzoyl peroxide (BPO) and 2,2'-azobisisobutyronitrile (AIBN) in the presence of eugenol. The induction period and initial rate of polymerization (IRP) were determined from polymerization curves of MMA using differential scanning calorimetry (DSC)

Synthesis and Characterization of Isothiocyanate Poly(Methyl Eugenol) and Thiosemicarbazide Poly(Methyl Eugenol)

Materials Science Forum, 2022
Abstract. This study investigates the synthesis, chemical, and physical properties of isothiocyanate poly(methyl eugenol) or IPME and thiosemicarbazide poly(methyl eugenol) or TPME. The IPME synthesis as a precursor was firstly carried out by reacting Methyl Eugenol (ME) with potassium hydrogen sulfate and potassium thiocyanate in chloroform solution ...

Comparative Analysis of In-Vitro Biological Activities of Methyl Eugenol Rich Cymbopogon khasianus Hack., Leaf Essential Oil with Pure Methyl Eugenol Compound

Current Pharmaceutical Biotechnology, 2020
Background:The essential oil of methyl eugenol rich Cymbopogon khasianus Hack. was evaluated and its bioactivities were compared with pure methyl eugenol. So far, methyl eugenol rich essential oil of lemongrass was not studied for any biological activities; hence, the present study was conducted.Objective:This study examined the chemical composition of

Effects of eugenol, α-terpineol, terpin-4-ol, and methyl eugenol on consumption of alfalfa pellets by sheep

Small Ruminant Research, 2007
Abstract Many secondary compounds are typically present in unpalatable shrubs on arid and semi-arid rangelands. However, the relationship between intake by livestock and concentration of individual chemicals has been examined for very few of these compounds. Four experiments were conducted to examine effects of individual volatile compounds on intake

Pharmacophagy of Methyl Eugenol by Males Enhances Sexual Selection of Bactrocera carambolae

Journal of Chemical Ecology, 2007
After pharmacophagy of methyl eugenol (ME), males of Bactrocera carambolae (Diptera: Tephritidae) produced (E)-coniferyl alcohol (CF) along with its endogenously synthesized pheromonal compounds. CF was shown to be released into the air by the ME-fed males only during the courtship period at dusk and attracted significantly more males and females than ...

Metabolism of Alkenebenzene Derivatives in the Rat. II. Eugenol and Isoeugenol Methyl Ethers

Xenobiotica, 1976
1. The metabolites of 3,4-dimethoxyallylbenzene (eugenol methyl ether) and 3,4-dimethoxypropenylbenzene (isoeugenol methyl ether) in the rat were identified and quantitatively determined by g.l.c. and g.l.c.-mass spectrometry. 2. The major metabolic reactions of 3,4-dimethoxyallylbenzene were oxidation of the allylic side chain to 2-hydroxy-3-(3,4 ...
