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.

The natural flavonoid bergenin was directly immobilized onto carboxylic acid functionalized controlled pore glass (carboxy-CPG) at 95% yield. Immobilized bergenin was brominated via chloroperoxidase in aqueous solution and then transesterified with vinyl butyrate in diisopropyl ether by subtilisin carslberg (SC)
