  An efficient convergent synthesis of adenosine-5′-N-alkyluronamides

  摘要：

  Herein we report an efficient synthesis of adenosine-5'-N-alkyluronamides in which an enzyme-mediated deacetylation reaction is a key to the selective modification of the 5'-N-position, prior to coupling the ribose and purine components via a microwave-assisted Vorbruggen coupling. This approach provides access to highly functionalised adenosines with 2- and N-6-substitutents, which can be incorporated before or after the ribose-coupling step. In all cases the microwave-assisted Vorbruggen coupling conditions afforded anomerically pure purine ribosides in good to excellent yields. (C) 2007 Elsevier Ltd. All rights reserved.
