一般描述
Vinyl butyrate causes the transesterification of natural flavonoid bergenin immobilized onto carboxylic acid functionalized controlled pore glass.
应用
Vinyl butyrate was used as acyl donor in the synthesis of citronellyl esters (acetate, propionate, butyrate, caprate and laurate) using immobilized Candida antarctical ipase B.

To reveal the functional role of Glu87 and Trp89 in the lid of Humicola lanuginosa lipase, site-directed mutagenesis at Glu87 and Trp89 was carried out. The catalytic performance of wild-type and mutated lipases was studied in transesterification reactions in cyclohexane

Enzymes are attractive catalysts for the production of optically active compounds in organic solvents. However, their often low catalytic activity in such applications hampers their practical use. To overcome this, we investigated the effectiveness of the covalent modification of alpha-chymotrypsin
Ionic liquids improve citronellyl ester synthesis catalyzed by immobilized Candida antarctica lipase B in solvent-free media.

Obtainment and testing of pure enantiomers are of great importance for bioactive compounds, because of the assessed implications of enantioselectivity in receptor-mediated responses. Herein we evaluated the use of biocatalysis to obtain enantiomerically pure β-lactam intermediates further exploited in the

We examined the activity of free Rhizopus oryzae lipase (ROL) and ROL immobilized on mesoporous materials in transesterification reactions in various dialkylimidazolium-cation based ionic liquids. For free ROL, the highest activity (0.39 U/mg protein) was obtained in [OMIm][PF(6)] followed by
