Process for the manufacture of an amino ester of formula (I) R1-O-C(O)-(CH2)n-NH2 (I) in which n is an integer from 10 to 15 from an unsaturated ester responding to formula (II) R1-O-C(O)-(CH2)m-CH=CH-R2 (II) in which R1 is either H or a saturated alkyl group containing from 1 to 5 carbon atoms; R2 is either H or an alkyl group containing from 1 to 10 carbon atoms, either saturated or containing 1 or 2 unsaturations and bearing optionally a hydroxyl, a carboxylic or an ester group, and m is equal to 7, 8, 9, 10 or 11; said process comprising: submitting the unsaturated ester of formula (II) to a catalytic cross-metathesis reaction with a pentenenitrile chosen among 2-pentenenitrile or 3-pentenenitrile in order to obtain a ester-nitrile responding to formula (III) R1-O-C(O)-(CH2)m-CH=CH-(CH2)p-CN (III) in which m is equal to 7, 8, 9, 10 or 11 and p is equal to 0 or 1, and submitting the obtained ester-nitrile of formula (III) to an hydrogenation in order to obtain the amino ester of formula (I).
制备公式(I)R1-O-C(O)-(
CH2)n-NH2的
氨基酯的方法,其中n是从10到15的整数,从响应公式(II)R1-O-C(O)-( )m-CH=CH-R2的不饱和酯中制备,其中R1为H或含有1至5个碳原子的饱和烷基基团;R2为H或含有1至10个碳原子的烷基基团,可以是饱和的,也可以含有1或2个不饱和度,并且可能带有羟基、羧基或酯基,m等于7、8、9、10或11;所述方法包括:将公式(II)的不饱和酯进行催化交叉烯烃反应,选择
2-戊烯腈或
3-戊烯腈之一,以获得响应公式(III)R1-O-C(O)-( )m-CH=CH-( )p-CN(III)的酯腈,其中m等于7、8、9、10或11,p等于0或1,并将所得的公式(III)的酯腈进行氢化,以获得公式(I)的
氨基酯。
