Abstract

Przedmiotem zgłoszenia są związki: (E)-oksym 2,4-dimetoksy-4'-fenylochalkonu o wzorze 2, (Z)-oksym 2,4-dimetoksy-4'-fenylochalkonu o wzorze 3. Zgłoszenie obejmuje także sposób ich jednoczesnego otrzymywania. Sposób ten polega na tym, że do substratu, którym jest 2,4-dimetoksy-4'-fenylochalkon o wzorze 1 dodaje się chlorowodorek hydroksyloaminy, bezwodny siarczan(VI) sodu, następnie mieszaninę rozpuszczalników organicznych a aparaturę wypełnia się azotem. Po rozpuszczeniu się substratów dodaje się pirydynę, co stanowi mieszaninę reakcyjną, którą zabezpiecza się przed dostępem światła i pozostawia w temperaturze od 18°C do 28°C na okres od 5 do 14 dni. Mieszaninę reakcyjną wylewa się do schłodzonej wody albo wody z lodem, a następnie prowadzi się ekstrakcję rozpuszczalnikiem organicznym niemieszającym się z wodą, osusza bezwodnym siarczanem(VI) magnezu i/lub bezwodnym siarczanem(VI) sodu, a rozpuszczalnik odparowuje się, następnie otrzymany ekstrakt oczyszcza się na kolumnie chromatograficznej.The subject of the application are: (E) -oxime 2,4-dimethoxy-4'-phenylchalcone of formula 2, (Z) -oxime 2,4-dimethoxy-4'-phenylchalcone of formula 3. The application also includes a method for their simultaneous preparation. . The method consists in adding hydroxylamine hydrochloride, anhydrous sodium sulfate to the substrate, which is 2,4-dimethoxy-4'-phenylchalcone of formula 1, then a mixture of organic solvents and the apparatus is filled with nitrogen. After the substrates have dissolved, pyridine is added, which is a reaction mixture that is protected from light and left at a temperature of 18 ° C to 28 ° C for a period of 5 to 14 days. The reaction mixture is poured into cooled water or ice water, followed by extraction with a water-immiscible organic solvent, dried over anhydrous magnesium sulfate and / or anhydrous sodium sulfate, and the solvent is evaporated, then the obtained extract is purified on a chromatographic column.
