摘要:A method used for synthesizing intermediates for use in the synthesis of carotenoids and carotenoid analogs, and/or carotenoid derivatives. In some embodiments, the invention includes methods for synthesizing optically active intermediates useful for the synthesis of optically active carotenoids. Synthesis of optically active carotenoids, in one embodiment, may be accomplished by forming an optically active dihydroxy intermediate from ketoisopherone. The optically active dihydroxy intermediate may be converted into optically active astaxanthin derivatives.

标 题 :Stereoselective synthesis of intermediates and synthesis of quinagolids
发明人：RYBERG PER; PINESCHI MAURO; COMPARINI LUCREZIA
权利人:FERRING BV
摘要:Disclosed is a method for preparing compounds with improved stereoselectivities. The described compounds are useful intermediates and may find particular application in the synthesis of compounds containing an octahydrobenzoquinoline moiety (e.g. an octahydrobenzo[g]quinoline moiety), such as quinagolide and its derivatives. Also disclosed is a method for stereoselectively (e.g. enantioselectively) preparing an intermediate used in the existing manufacturing process for the synthesis of quinagolide this intermediate also finding utility in the synthesis of other compounds containing an octahydrobenzo[g]quinoline moiety, in particular those having a substituent at the 3- position on the octahydrobenzo[g]quinoline.

摘要:The invention relates to a process for the electrochemical synthesis of alkali metal alcoholates (alkoxides) and/or for the regeneration of the catalyst from methyl formate synthesis from alcoholic solutions of salts of alkali metals in an electrolysis apparatus with an ion-selective membrane. The electrolysis is carried out in the presence of a defined quantity of a potassium salt or sodium salt of a perfluoroalkanesulphonic acid accompanied by the use of non-oxidisable anode material and with a membrane based on a sulphonated styrene-divinylbenzene copolymer. The process enables an increase in the selectivity of the procedure and a continuous synthesis.
