A simple approach for the selective enzymatic synthesis of dilauroyl maltose in organic media
摘要:
A selective synthesis of dilauroyl maltose was developed using lipase-catalyzed condensation of lauric acid and maltose in two-solvent Mixtures. The characteristics of different solvent combination were tested and it was found that the combination of acetone with n-hexane has a good selectivity for the synthesis of dilauroyl maltose. The highest diester conversion of 69% (i.e. 36.5 g/L of dilauroyl maltose) was obtained under optimal conditions: 25.65 g/L maltose, 60 g/L lauric acid, 60 g/L molecular sieve and 10 g/L lipase at 150 rpm and 50 degrees C for 72 h in 10 mL of mixed solvent of acetone:n-hexane (60:40, v/v).

the facile enzymatic preparation of a homologous series of 6′-O-acylmaltose esters and an in-depth evaluation of them revealing that their surfactant properties and thermal stabilities are largely determined by the length of the fattyacidchain. In the first such comparison, we show that the foaming and emulsifying effects of certain of these maltose monoesters are superior to those of their sucrose-derived

The enzymatic acylation of several di- and trisaccharides with acyl donors ranging from 8 to 18 carbon atoms was carried out by transesterification with the corresponding vinyl esters. The reaction was performed in 2-methyl-2-butanol/dimethylsulfoxide mixtures using the lipase from Humicola lanuginosa (immobilized on Celite). Maltose, maltotriose and n-dodecyl maltosides were specifically acylated in the primary hydroxyl of the non-reducing-end glucose moiety; the acylation of leucrose occurred preferentially in the primary hydroxyl of the glucose ring.
