Oxidation of menthone oxothiolane
Chemistry of Natural Compounds, 2008meta-Chloroperoxybenzoic acid (m-ClPBA) was shown to be an oxidant for two stereoisomers of menthone oxothiolane. The effect of steric factors on the ability to oxidize the sulfide group was found. Oxidation of (5S,6S,9R)-6-isopropyl-9-methyl-1-oxo-4-thiaspiro[4.5]-decane to the sulfone was prevented by the steric proximity of an isopropyl group to the

Menthone Semicarbazides and Thiosemicarbazides as Anticonvulsant Agents
Medicinal Chemistry, 2010A series of novel (+/-) 3-menthone semi carbazides (1-7) and thiosemicarbazides synthesized using an appropriate synthetic route and characterized by thin layer chromatography and spectral analysis. The anticonvulsant activity of synthesized compounds was established after intraperitoneal administration in three seizure models in mice which include ...

Asymmetrical oxidation of menthone dithiolane
Russian Journal of Organic Chemistry, 2008Asymmetrical oxidation was performed of menthone dithiolane obtained in 95–98% yield by condensation of menthone with 1,2-ethanedithiol in the presence of boron trifluoride etherate. 6-Isopropyl-9-methyl-1,4-dithiaspiro[4,5]decane-1,4-dioxide (yield 5–55%) and 6-isopropyl-9-methyl-1,4-dithiaspiro[4,5]-decane-1,1,4-trioxide (yield 65–70%) were ...

Chiral perrocenylalkylamines from (-)-menthone
Tetrahedron, 1986Abstract Three enantiomerically pure ∝-ferrocenylalkylamines are directly obtained from (-)-menthone. The isomerizations of the ∝-ferrocenylalkyl carbocation intermediates are studied and exploited in stereoselective syntheses. These carbocations are the basis of the configurational assignment of the amines.

Effect of cyclodextrin complexation on the reduction of menthone and isomenthone
Journal of Inclusion Phenomena, 1987The β- and γ-cyclodextrin complexation of menthone and isomenthone was found to modify the ratio of epimeric menthol products formed upon a NaBH4/MeOH reduction of these ketones.

Stereoselectivity of electroreduction of a menthone-isomenthone mixture
Russian Journal of Applied Chemistry, 2009Electroreduction of an equilibrium menthone-isomenthone mixture at a controlled potential in a diaphragm cell on various cathodes was studied. The influence exerted by the nature of a solvent and of an electrode, electrode material, and various additives on the reduction stereoselectivity of ketones was examined.
