    • The invention relates to a method for the synthesis of amino acids/esters of general formula NH2—(CH2)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 R1—(CH2)m—CH═CH—(CH2)p—COOR in which R1 is H, CH3 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 R2—CH═CH—R3 in which R2 is either H or CN and R3 is CN or CH2NH2, provided that if R2 is CN, R3 can be only CN, and finally converting the resulting product of the general formula R3—CH═CH—(CH2)p—COOR into an amino-acid, either by hydrogenation, or by hydrogenation of the triple terminal bond, or by amination of the double terminal bond.
    • 本发明涉及一种合成通式为NH2-(CH2)n-COOR的氨基酸/酯的方法,其中n为5至14的整数,R为H或包含1至4个的烷基 碳原子,天然长链单不饱和脂肪酸或每分子包含至少10个相邻碳原子的酯,所述方法包括:首先将所述天然长链脂肪酸或酯转化成单不饱和脂肪酸/ 通式R1-(CH2)m-CH = CH-(CH2)p-COOR的酯,其中R1是H,CH3或COOR基团,m是0和14之间的整数,p是2和11之间的整数 然后将其与式R2-CH = CH-R3的化合物进行交叉催化复分解反应,其中R2是H或CN,R3是CN或CH2NH2,条件是如果R2是CN,则R3可以仅为CN ,最后通过氢化或通过氢化将得到的通式R3-CH = CH-(CH2)p-COOR的产物转化为氨基酸 三末端键的基因,或通过双末端键的胺化。
