Patent ID: 8377661

Claim:
A process for synthesizing ω-aminoalkanoic acids, or esters thereof, from monounsaturated natural fatty acids, comprising; converting a monounsaturated natural fatty acid having the formula R—(CH 2 ) m —CH═CH—(CH 2 ) p —COOH, in which R is either H or CH 3 , m has a value of between 0 and 11 and p has a value of between 2 and 13, into an unsaturated α-ω-diacid or diester, either by a homometathesis reaction or by fermentation, then, subjecting the unsaturated α-ω-diacid or diester to an oxidative cleavage reaction so as to form a single α-ω-aldehyde-acid or ester or two different α-ω-aldehyde-acids or esters of the general formula CHO—(CH 2 ) n —COOH, in which n is equal to m and/or p, and then, converting the resulting product, by reductive amination, into an ω-amino acid of formula NH 2 —(CH 2 ) n+1 —COOH.
