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.
A hetero Diels–Alder approach to the synthesis of the first angucyclinone and angucycline 5-aza-analogues
摘要:
The synthesis of two new heterodienes and their regioselective [4+2]cycloaddition reactions with several bromo-naphthoquinones allowed us to prepare the first angucyclinone and angucycline 5-aza-analogues. (C) 2004 Elsevier Ltd. All rights reserved.
