Abstract
A process for synthesizing an ω-amino acid compound of formulaHOOC—(CH)—CHNH,wherein 4≤r≤13 from a monounsaturated fatty nitrile compound of formulaCH═CH—(CH)—CNthe process comprising: 1) a step of hydroformylation of the mono unsaturated fatty nitrile compound by reacting said nitrile with carbon monoxide and di hydrogen 5e-a5 to obtain a nitrile aldehyde compound of formula HOC—(CH2)r+2-CN, then 2) a step of oxidation, in the presence of dioxygen, of the nitrile aldehyde compound to obtain a corresponding nitrile acid compound of formula HOOC—(CH2)r+2-CN, and 3) a step of reduction of the nitrile acid compound to give an w-amino acid of formulaHOOC—(CH)—CHNH.
