  Total synthesis of masked Alternaria mycotoxins—sulfates and glucosides of alternariol (AOH) and alternariol-9-methyl ether (AME)

  摘要：

  The synthesis of different protected alternariol derivatives using intramolecular cyclization of iodoresorcylic acid phenyl esters by palladium-catalyzed C-H activation as key step is presented. Furthermore, chemical sulfation and glucosylation were applied for the preparation of conjugated Alternaria mycotoxins. These compounds are suspected to be formed during metabolism in contaminated plants. Therefore, all synthetic conjugates prepared within this work serve as reference materials for further studies in the fields of bioanalytics and toxicology of mycotoxins. (C) 2013 Elsevier Ltd.
