Neue Oleochemikalien aus ungesättigten Fettsäuren durch CC‐Verknüpfungsreaktionen

Hydroaminomethylation of fatty acids with primary and secondary amines — A new route to interesting surfactant substrates

“…1 shows the results for the reaction of oleic acid ethyl ester (1) with the primary amines hexylamine (3), benzylamine (4), aspartic acid diethyl ester (5), valinol (6) and with the secondary amine morpholine (7), respectively (reaction [1][2][3][4][5]. Although the conditions are not yet carefully optimised, all reactions proceed under moderate reaction conditions with good to excellent yields and with high selectivity to the corresponding secondary or tertiary amines (Fig.…”

“…The products possess interesting chemical and physical properties making them attractive for many industrial applications. However, only little work has been done on the synthesis of such compounds [1][2][3][4][5]. Recently we have published our results on the ene-reaction and the Diels-Alder reaction of unsaturated fatty esters [6][7][8].…”

Addition of glyoxylic acid ethyl ester to unsaturated fatty acid derivatives

“…New oleochemicals with interesting chemical and physical properties can be synthesized by C,C-bond forming reactions [1][2][3]. Besides, reactions leading to fatty acid derivatives with an alkyl-branched chain [4], Diels-Alder, and ene reactions offer the possibility to introduce functional groups into the carbon chain [5][6][7].…”
