Abstract

Zgłoszenie ujawnia (2E)-2-[(6S,3R)-3-metylo-2-(propan-2-ylo)cykloheksylideno] butanian etylu o wzorze 1, znajdujący zastosowanie w produkcji perfum, artykułów spożywczych, artykułów kosmetycznych. Przedmiotem zgłoszenia jest również sposób wytwarzania (2E)-2-[(2S,5R)-5-metylko-2-(propan-2-ylo) cykloheksylideno]butanianu etylu o wzorze 1, polegający na tym, że (2S,5R)-2 isopropylo-5-metylocykloheksanon, poddaje się reakcji redukcji z użyciem 2-(dietoksyfosforylo)butanianu etylu jako reagenta i tetrahydrofuranu jako środowiska reakcji, przy czym reakcja prowadzona jest w łaźni lodowej, a po zakończeniu procesu odparowuje się rozpuszczalniki, a produkt oczyszcza się przy wykorzystaniu chromatografii kolumnowej.The application discloses ethyl (2E) -2 - [(6S, 3R) -3-methyl-2- (propan-2-yl) cyclohexylidene] butanoate, used in the production of perfumes, foodstuffs, cosmetics. The subject of the application is also a process for producing ethyl (2E) -2 - [(2S, 5R) -5-methyl-2- (propan-2-yl) cyclohexylidene] butanoate of the formula (2S, 5R) -2-isopropyl-5-methylcyclohexanone, is subjected to a reduction reaction using ethyl 2- (diethoxyphosphoryl) butanoate as a reactant and tetrahydrofuran as a reaction medium, the reaction being carried out in an ice bath, and after the end of the process the solvents are evaporated and the product is purified using column chromatography.
