Известен способ получени пентадека- нопидов обшей формулы fl. По этому способу 2-оксабицикло(4, lO,0)гeкc9дeкa-l (6)-eн или его метипьный аналог окисл ют перуксусной кислотой, полученный промежуточный продукт обрабатывают смесью сульфита и бисульфита натри , что приводит к четырехкомпонентной смеси, которую каталитически гидрируют над ни- келем Рене и после .разгонки на высокоэффективной колонке получают целевой фодукт с выходом 54-64%. Недостатками этого способа вл ютс приме неиие взрывоопасной перуксусной кислоты, низкий выход целевого продукта, а также трудность разделени многотсомпопентной реакционной смеси (применение «Р.ЮОКОЭ Ьфективных ректификационных KOHOMFI).A known method for the preparation of pentadecanopeds of the general formula fl. In this method, 2-oxabicyclo (4, lO, 0) hexadecane-1 (6) -en or its methyl analogue is oxidized with peracetic acid, the resulting intermediate product is treated with a mixture of sulfite and sodium bisulfite, which leads to a four-component mixture that is catalytically hydrogenated over Rene's nickel and after distillation on a high-performance column receive the target product with a yield of 54-64%. The disadvantages of this method are the application of explosive peracetic acid, the low yield of the target product, as well as the difficulty of separating the multi-component reaction mixture (use of R.OKOE B effective rectifying KOHOMFI).
