PROCESS FOR PREPARING SATURATED AMINO ACIDS OR SATURATED AMINO ESTERS COMPRISING A METATHESIS STEP

摘要

The subject matter of the invention is a process for synthesizing a saturated long-chain a,?-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 step, acting as a hydrogenation catalyst.
