  Synthesis of 5-aza-analogues of angucyclines: manipulation of the 2-deoxy-C-glycoside subunit

  摘要：

  Based on a heterocyclic Diels-Alder strategy, a concise synthesis of 5-aza-analogues of angucyclines bearing a 2-deoxy-C-glycoside subunit is reported. Starting from a common intermediate, a peracetylated D-2-deoxyglucose could be linked to carbons C9 or C10 of the tetracyclic framework. Further manipulations of the sugar residue allowed the installation of bromo and azido substituents at carbon C6'. (c) 2005 Elsevier Ltd. All rights reserved.
