Reaction Conditions:
with immobilized Candida antarctica Lipase B in neat (no solvent) at 60; for 4 h;Green chemistry;Enzymatic reaction;
Steps:
2.6 Esterification of ALA in preparative scale
TEOF 12 ml (0.072 mol) and 1 g of Novozym 435 were added to ALA 20 g (0.072 mol). The mixture added of 10 μl of ethanol and incubated at 60 °C under shaking at 300 rpm. After 4 h the GC analysis evidenced the complete conversion of the substrate, and the reaction was stopped by filtering off the enzyme. The obtained oil, kept under vacuum (2 mbar) for 1 h at rt, furnished 22 g of ALA ethyl ester (in >99% yield), which nature was confirmed by comparison in GC analysis with an authentic sample.
