ΕΝΔΟΜΟΡΙΑΚΗ ΦΩΤΟΚΥΚΛΟΠΟΙΗΣΗ ΤΗΣ ΚΑΡΒΟΝΗΣ ΠΡΟΣ ΚΑΡΒΟΝΟΚΑΜΦΟΡΑ
THE QUANTUM YIELDS OF THE PHOTOCYCLOADDITION OF CARVONE (I) TO CARVONECAMPHOR (2) (TYPE) HAVE BEEN DETERMINED IN NON POLAR AND POLAR SOLVENTS, UNDER NITROGEN AND IN AIR-EQUILIBRATED SOLUTIONS. QUENCHING BY OXYGEN HAS BEEN OBSERVED ONLY IN NON POLAR SOLVENTS, BENZENE 01 --> 2=0.0025 UNDER NITROGEN …

Chirality Determination Using Three-Wave Mixing Microwave Spectroscopy
… first molecule studied with this instrument was carvone, whose traditional rotational spectrum is denominated by internal rotation splittings from two non-equivalent methyl rotors. This M3WM experiment marked the first time a M3WM experiment was completely operable in the 6-18 GHz region of the …

Stability of aseptically packaged food as a function of oxidation initiated by a polymer contact surface
… no polymer was also measured. Production of carvone and carveol were used as an index for oxidation. No polymer and UV treated samples showed significantly (P<0.05) higher levels of calVone and calVeol than samples containing untreated and HzOz treated LDPE. Samples containing no polymer …

Approaches Towards a Total Synthesis of Daphenylline
… overall yield from commercially available (S)-carvone through [3,3]-allyl cyanate-to-isocyanate rearrangement, intramolecular Heck Reaction, and Intermolecular Diels-Alder/benzannulation strategies. Efforts towards the synthesis of daphenylline’s D ring are discussed. A terse introduction to …

Analysis of potent odorants in spearmint oils
… the odorants. Of the 85 odorants detected, R-(-)-carvone was the most potent odorant in all three spearmint oils. Eugenol, ethyl-2-methyl butyrate, β-damacenone, and (3E,5Z)-1,3,5-undecatriene were also identified to be predominant odorants in the spearmint oils. New potent odorants not previously …

The role of terpenes as protectors of the potato crop
… natural solution to sprouting inhibition. S-Carvone has been shown to suppress sprouting in potato varieties, and importantly, has no effect on processing quality of potatoes. Cyclodextrins have been studied as a possible mechanism for improving application efficiency of sprouting inhibitors. …

Progettazione, sintesi e valutazione biologica di nuovi ligandi come potenziali agenti terapeutici per il trattamento del dolore persistente
… e/sigma. I nuovi ligandi, derivati dall’R-Carvone, sono stati valutati mediante saggi di competition binding sui recettori oppioidi e sigma e attualmente sono ulteriormente in studio.

Properties of Absorbent Polymer Extractants for the Selective Removal of Target Molecules from Fermentation Systems
… representative target molecules, carveol and carvone, were studied using commercial block copolymers and their representative homopolymer components. Target molecule affinity improved at low molecular weights in the absence of polar homopolymer end-groups. End-group polarity had an effect …
