标 题 :Synthesis of esters of acetylenic alcohols
发明人：CLOSE RALPH E; OROSHNIK WILLIAM
权利人:SCM CORP
摘要:A process for the synthesis of perfume products, Vitamin E and intermediates described herein involving a coupling reaction. For instance, a process for the synthesis of dehydrophytol and Vitamin E comprising forming a C15 acetylene from hexahydropseudoionone and then coupling said acetylene with 1-acetoxy-4-chloro-3-methylbut-2-ene to form a C20 acetoxy-enyne. The latter is readily subjected to partial hydrogenation and saponification in that order to form a dehydrophytol, a useful intermediate for the synthesis of Vitamin E and other products.

标题:Synthesis of acetylenic compounds useful in preparing dehydrophytols and Vitamin E
发明人：CLOSE RALPH E; OROSHNIK WILLIAM
权利人:SCM CORP
摘要:A process for the synthesis of an acetylenic hydrocarbon from an acetylenic carbinol which involves first replacing the hydroxyl group of the carbinol with a halogen to form a propargylic halide, dehalogenating the propargylic halide to form an allene, and isomerizing said allene to the desired acetylene. The present invention is particularly useful in the synthesis of Vitamin E.

摘要:An improved method of producing 3,5,5-trimethylcyclohex-2-ene-1,4-dione (KIP) by the oxidation of 3,5,5-trimethylcyclohex-3-ene-1-one ( beta -IP) in the presence of managansalene-like catalysts and certain catalytic additives. Byproducts:uct in the synthesis of trimethylhydroquinone, an initial substance in the synthesis of vitamin E. Furthermore, KIP is an initial compound for the synthesis of various carotinoids.
