标 题 :Efficient synthesis of amines and amides from alcohols and aldehydes by using cascade catalysis
发明人：CÓRDOVA ARMANDO; BERGLUND PER; ANDERSON MATTIAS; AFEWERKI SAMSON
权利人:XP CHEMISTRIES AB
摘要:The present invention relates generally to an eco-friendly methodology for the conversion of alcohols and aldehydes to amines and amides using an integrated enzyme cascade system with metal- and organocatalysis. More specifically, the present invention relates to synthesis of capsaicinoids starting from vanillin alcohol and using a combination of an enzyme cascade system and catalysts. Furthermore, the method also relates to synthesis of capsaicinoids derivatives starting from vanillin alcohol derivatives and using a combination of an enzyme cascade system and catalysts.

标 题:Methods for the synthesis of fatty diacids by the metathesis of unsaturated diacids obtained by fermentation of natural fatty 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 diacids of general formula ROOC—(CH 2 ) n —(CHâ•?CH) a —(CH 2 ) m COOR 1 in which n and m are identical or different and each represent an integer such that their sum is between 6 and 15, a is an index of 0 or 1, and R and R 1 are H or an alkyl radical with 1 to 4 carbon atoms, from long-chain mono-unsaturated natural fatty acids or esters having at least 10 adjacent carbon atoms per molecule of the general formula CH 3 —(CH 2 ) p —CHâ•?CH—(CH 2 ) q —COOR, p and q, being identical or different and representing indices between 2 and 11, wherein said method comprises the first step of oxidizing by fermentation said natural fatty acid or ester, using a microorganism, such as a bacterium, a yeast, or a fungus, into at least one unsaturated dicarboxylic acid or dicarboxylate, the second step of submitting the product from the first step to a metathesis crossed with a compound of formula R 2 OOC—(CH 2 ) x —CHâ•?CH—R 3 , in which R 2 is H or an alkyl radical with 1 to 4 carbon atoms, x is 0 or 1 or 2, and R 3 is H, CH 3 or COOR 2 , in order to obtain the unsaturated compound of formula ROOC—(CH 2 ) q —CHâ•?CH—(CH 2 ) x —COOR 2 , and the third optional step of converting the usaturated compound into a saturated compound by hydrogenation of the double bond.
