title: Simple and efficient solid support scavenging of excess acyl donors after enzymatic acylations in organic solvents.
abstract: A simple and efficient method for removing excess acyl donors following enzymatic acylations in organic solvents was developed. This method is based on selective chemical scavenging of acyl donors using an amino-functionalized solid support, and does not affect the desired acylated product. A wide variety of different acyl donors, including vinyl and trifluoroethyl esters and vinyl carbonates, can be quantitatively removed by this method, thus providing a simple and highly efficient tool for purification of reaction products after enzymatic acylation.
