Enzymatic regioselective synthesis of sucrose acrylate esters

Enzymatic regioselective synthesis of sucrose acrylate esters

Biotechnology Letters 22(1): 39-42

Using a protease (at 100 g l-1) from Bacillus licheniformis, enzymatic acryloylation of sucrose (1 M) with vinyl acrylate (4 M) was carried out in anhydrous pyridine and yielded sucrose acrylate esters with more than 90% of sucrose converted in 24 h. After 5 days of reaction, the ester products consisted of 70% sucrose monoacrylate and 30% sucrose diacrylate. The monoester product was a sucrose 1'-acrylate and the diester products consisted of sucrose 6,1'-diacrylate and sucrose 6',1'-diacrylate in the ratio of 3:2.
