Abstract

Przedmiotem wynalazku jest 2-hydroksy-5-metylo-9-oksabicyklo [4.3.0]nonan-8-on o wzorze o mało intensywnym, owocowym zapachu, z lekką nutą ziołową oraz sposób jego otrzymywania na drodze syntezy chemicznej z estru etylowego kwasu (4-metylocykloheks-2-en-1-ylo)octowego, który jest mieszaniną diastereoizomerów. W wyniku epoksydacji w rozpuszczalniku organicznym otrzymuje się ester etylowy kwasu (4-metylo-2,3-epoksycykloheks-1-ylo)octowego. Otrzymany związek poddaje się reakcji laktonizacji kwasowej otrzymując hydroksylakton. Wynalazek może znaleźć zastosowanie w przemyśle kosmetycznym jako składnik kompozycji zapachowych lub w przemyśle spożywczym jako aromatyczny dodatek do żywności.The subject of the invention is 2-hydroxy-5-methyl-9-oxabicyclo [4.3.0] nonan-8-one with a formula with a low intense, fruity aroma, with a slight herbal note and a method of obtaining it by chemical synthesis from acid ethyl ester ( 4-methylcyclohex-2-en-1-yl) acetic acid, which is a mixture of diastereomers. Epoxidation in an organic solvent yields (4-methyl-2,3-epoxycyclohex-1-yl) acetic acid ethyl ester. The obtained compound is subjected to an acid lactonization reaction to obtain hydroxylactone. The invention may find use in the cosmetics industry as an ingredient in fragrance compositions or in the food industry as an aromatic food additive.
