В присутствии ацетата натри в расплаве при 160-170° С в инертной атмосфере.In the presence of sodium acetate in the melt at 160-170 ° C in an inert atmosphere.
Целевой продукт реакции выдел ют известными методами с выходом 66%. Строение 2-олеоилциклагексан-1,3-диона подтверждено его физико-химическими данными и сравнением их с описанными характеристиками природного продукта, а также других 2-ацилциклогексан-1,3-дионов 3,The desired reaction product was isolated by known methods with a yield of 66%. The structure of 2-oleoyl cyclahexane-1,3-dione is confirmed by its physicochemical data and their comparison with the described characteristics of the natural product, as well as other 2-acylcyclohexane-1,3-diones 3,
Пример. Смесь 1,2 г (3,2 мМоль) 3-олеоилокси-2-циклогексен-1-она и 0,27 г (3,3 ммоль) безводного плавленного ацетата натри нагревают до образовани однородной жидкой массы при 160-170° С в 30 мин в инертной атмосфере. Полученный Тёмнокрасный плав после охлаждени раствор ют в 150 мл эфира и раствор дважды промывают водой (по 50 мл) и сушат сульфатом магни . Остаток после удалени растворител подвергают хроматографическому разделению на колонке с .силикагелем марки Л 40/100 |i. При элюировании системой эфир-гексан 1 :2 полу-чают 0,8 г (66%) 2-олевилциклогексан-1,3диона в виде бесцветного масла (кристал лизуетс при хранении в холодильнике, т. пл. 10° С).Example. A mixture of 1.2 g (3.2 mM) of 3-oleoyloxy-2-cyclohexen-1-one and 0.27 g (3.3 mmol) of anhydrous fused sodium acetate is heated to form a homogeneous slurry at 160-170 ° C. 30 min in an inert atmosphere. The obtained dark red melt after cooling is dissolved in 150 ml of ether and the solution is washed twice with water (50 ml each time) and dried with magnesium sulfate. The residue after removal of the solvent is subjected to chromatographic separation on a column with silica gel brand L 40/100 | i. When elution with a 1: 2 ether-hexane system, 0.8 g (66%) of 2-olevylcyclohexane-1,3-dione is obtained as a colorless oil (crystallized during storage in a refrigerator, mp. 10 ° C).
