The lipase-catalysed reaction of aliphatic amine with ethyl propiolate was investigated using benzylamine as reference amine. The conditions were optimised to favour the 1,2-addition, i.e., formation of N-benzylprop-2-ynamide, versus the 1,4-addition. Immobilised Candida antarctica lipase (CALB) was found to be the most efficient enzyme, and the reactions were performed in solvents, such as tBME,...
Candida antarctica lipase is well known to convert amines and alcohols into amides and esters. This report describes the development of a solvent-free enzymatic process for the production of fatty alkanolamides. The aminolysis of linoleyl ethyl ester with several aminoalcohols from C2 to C6 (linear or branched compounds), and the very high selectivity of amide compounds have been observed.Our investigation...
