Conformational energy of (+)-pulegone

Journal of the Chemical Society D: Chemical Communications, 1971
Temperature-dependent circular dichrosim measurements on (+)-pulegone enabled us to estimate its conformational energy.

PHOTOCHEMISTRY OF FUKINONE AND PULEGONE

Chemistry Letters, 1972
Abstract Fukinone (I), a sesquiterpenic ketone containing a conjugated double bond in cisoid form, on photolysis in methanol solution gave methyl ester (III), stereoisomeric cyclobutanols (IVa and Va), and methyl ether (VI). Photolysis of pulegone (II), a monoterpenic analogue of I, afforded quite similar results.

Circular dichroism studies. The pulegone oxides

Journal of the Chemical Society C: Organic, 1970
The optical rotatory dispersion and circular dichroism of the pulegone oxides in a variety of solvents are reported. The results are analysed in terms of the possible equilibria.

Metabolic fate ofS-(-)-pulegone in rat

Xenobiotica, 1998
1. S-(-)-pulegone was administered orally to rat (250 mg/kg) and the nature of the urinary metabolites was investigated. Eleven metabolites, namely S-(-)-menthofuran, piperitone, piperitenone, p-cresol, 5-hydroxypulegone, 4-methylcyclohexenone, 3-methylcyclohexanone, isopulegone, pulegol, 7-hydroxypiperitone and benzoic acid, have been isolated from ...

The favorskii rearrangement of pulegone oxide

Tetrahedron, 1967
Abstract The stereoisomeric pulegone oxides I and II undergo a stereospecific Favorskii rearrangement when treated with sodium methoxide in refluxing glyme. The major products are identified by spectroscopic measurements and by conversion to pulegenic esters (X A,B) and puleganolides (XIII A,B).

Favorskii rearrangement of the pulegone epoxides

Tetrahedron, 1967
Abstract The pulegone epoxide I, with sodium ethoxide in ethanol, gives as the major product, the ‘puleganolic’ acid III; similarly epoxide V gives the ‘puleganolic’ acid VII with the puleganolide IX. The major products obtained from epoxide I, in aqueous ethanol, are a ‘normal’ hydroxy acid XI together with III, and from epoxide V, a ‘normal ...

Inhibition of acetylcholinesterases by pulegone-1,2-epoxide

Pesticide Biochemistry and Physiology, 1985
Abstract Toxicological observations indicate that pulegone-1,2-epoxide, isolated from the medicinal plant, poleo (Lippia stoechadifolia), is an insect neurotoxin. These observations prompted studies of the action of pulegone-1,2-epoxide on acetylcholinesterase activity.

Synthesis and Properties of Chiral Pyrazolidines Derived from (+)‐Pulegone

Chemistry – A European Journal, 2010
AbstractSeveral enantiomerically pure N(2)‐substituted octahydroindazoles were prepared as bicyclic pyrazolidine derivatives of (+)‐pulegone. Condensation of pulegone with hydrazine delivered a hexahydroindazole intermediate, which underwent N(2)‐substitution with various electrophiles (alkyl halides, acyl chlorides, phenyl isocyanate). The resulting N(

Biological activities of pulegone

1998
High antibacterial and antifungal activity of pulegone has been confirmed by broth dilution method. It has also been found that pulegone has short-term stimulating effect on diuresis in rats.

[Quantitative analysis of pulegone in Herba Schizonepetae].

Zhongguo Zhong yao za zhi = Zhongguo zhongyao zazhi = China journal of Chinese materia medica, 2006
To establish the determination method of pulegone in Herba Schizonepetae.HPLC method was developed for the determination of pulegone in Herba Schizonepetae. The separation was performed on C18 column with MeOH-H2O (80:20) as a mobile phase. The detection wavelength was set at 252 nm.The quantitation of pulegone in Herba Schizonepetae varied from 0.2-0 ...
