标题 :Process for the synthesis of w-Unsaturated nitrile-acid/ester in which two types of cross metathesis are alternated consecutively swing process
发明人：DUBOIS JEAN-LUC; COUTURIER JEAN-LUC
权利人:ARKEMA FRANCE
摘要:The invention relates to a process for the synthesis of a monounsaturated nitrile-ester (acid) by cross metathesis starting from an unsaturated compound I comprising at least one trivalent nitrile, acid or ester functional group, characterized in that it comprises a stage in which two types of cross metathesis are alternated consecutively:n a first type of cross metathesis cm1 with an acrylic compound II chosen from acrylonitrile, acrylic acid or an acrylic ester, one of the compounds I or II comprising a nitrile functional group and the other of these compounds II or I comprising an acid or ester functional group, and a second type of cross metathesis cm2 with a light C 2 to C 4 alkene compound III, preferably with ethylene. nn The invention also relates to a process for the synthesis of an α,ω-amino ester (acid) obtained by a process comprising a stage in which the two types of cross metathesis defined above are alternated consecutively, followed by a hydrogenation stage.

标题 :Method for the synthesis of omega-amino-alkanoic acids
发明人：DUBOIS JEAN-LUC
权利人:DUBOIS JEAN-LUC; ARKEMA FRANCE
摘要:The invention relates to a method for the synthesis of amino acids/esters of general formula NH 2 —(CH 2 ) n —COOR in which n is an integer between 5 and 14, and R is either H or an alkyl radical including from 1 to 4 carbon atoms, from natural long-chain mono-unsaturated fatty acids or esters including at least 10 adjacent carbon atoms per molecule, said method comprising: first converting, if necessary, said natural long-chain fatty acid or ester into a monounsaturated fatty acid/ester of general formula R 1 —(CH 2 ) m —CHâ•?CH—(CH 2 ) p —COOR in which R 1 is H, CH 3 or a COOR radical, m is an integer between 0 and 14 and p is an integer between 2 and 11, then submitting the latter to a crossed catalytic metathesis reaction with a compound of formula R 2 —CHâ•?CH—R 3 in which R 2 is either H or CN and R 3 is CN or CH 2 NH 2 , provided that if R 2 is CN, R 3 can be only CN, and finally converting the resulting product of the general formula R 3 —CHâ•?CH—(CH 2 ) p —COOR into an amino-acid, either by hydrogenation, or by hydrogenation of the trple terminal bond, or by amination of the double terminal bond.

权利人:ARKEMA FRANCE
摘要:The invention relates to a method for the synthesis of short-chain ω-unsaturated fatty acids of general formula CH2â•?CH—(CH2)n—COOR in which n is an integer between 2 and 11 and R is H or an alkyl radical containing from 1 to 4 carbon atoms, from long-chain monounsaturated fatty acids or esters of formula CH3—(CH2)m—CHâ•?CH—(CH2)p—COOR in which m and p are integers, either identical or different, between 2 and 11, such that the molecule contains at least 10 adjacent carbon atoms in the main chain, said method comprises the first step of submitting the long-chain monounsaturated fatty acid charge to an oxidation by fermentation using a microorganism containing enzymes of oxygenase type, thus leading to the formation of α,ω-diacids, and then a second step of subjecting the product from the first step to a catalytic metsthesis crossed with ethylene for forming two short-chain ω-unsaturated fatty acids having a main chain length relative to that of the starting unsaturated fatty acid or ester of beteen 0.2 and 0.8, and preferably 0.35 and 0.75.

标题 :Process and intermediates for the synthesis of Vitamin D3 metabolites and chenodeoxycholic acid
发明人：BATCHO ANDREW D; USKOKOVIC MILAN R; WOVKULICH PETER M
权利人:HOFFMANN LA ROCHE
摘要:The present disclosure is directed to a process for the synthesis of chenodeoxychloic acid, 25-hydroxycholesterol and 1α,25-dihydroxycholesterol from 17-keto steroids. A cholic acid side chain is stereospecifically introduced by reaction of the appropriate 17-keto steroid with ethyltriphenylphosphonium halides to produce the 17-ethylidene derivative which is allowed to react with acrylic acid esters or propiolic acid esters followed by hydrogenation.

摘要:The present disclosure is directed to a process and intermediates for the synthesis of Vitamin D 3 metabolites such as 1,25-dihydroxycholecalciferol, 25-hydroxycholecalciferol and 24R,25-dihydroxycholecalciferol from 17-keto steroids via intermediates having the natural steroid configuration at the 20-position. These novel intermediates are prepared from 17-keto steroids by reaction with ethyltriphenylphosphonium halides followed by reaction with formaldehyde to form comounds having the natural steroid configuration at the 20-position and which are suitable substrates for the preparation of the aforementioned Vitamin D 3 metabolites.
