摘要：

Selecting the right partner faster: In protein chemoselective conjugation, the use of levulinic acid for ketone introduction leads to slow oxime formation and poor yield because of internal cyclization, especially at low concentrations. A mechanism for cyclization is proposed and alternative keto-acids have been tested. These showed faster formation of oximes without side products. Copyright © 2013 WILEY-VCH Verlag GmbH & Co.
