The subject matter of the invention is a process for synthesizing a saturated long-chain o.,0)-amino ester (acid) obtained in a first step by cross-metathesis between an acrylic first compound and a monounsaturated second compound comprising at least one nitrile, acid or ester trivalent function, one of these compounds comprising a nitrile function and the other an acid or ester function, in the presence of a ruthenium carbene metathesis catalyst, and in a second step by hydrogenation of the monounsaturated nitrile ester (acid) obtained in the presence of the metathesis catalyst of the preceding stop, acting as a hydrogenation catalyst.
发明的主题是一种合成饱和长链O.,0)-氨基酯(酸)的过程,该过程首先通过交叉复分解在丙烯酸第一种化合物和至少含有一种腈、酸或酯三价功能的单不饱和第二种化合物之间进行,其中一种化合物含有腈功能,另一种化合物含有酸或酯功能,在钌卡宾复分解催化剂的存在下,然后在第二步中,通过氢化在前一步中获得的单不饱和腈酯(酸),在前一步中的复分解催化剂作为氢化催化剂的作用下。
