  Effective and one-step stereo-controlled synthesis of benzyloxylated-diiodopentanes for the synthesis of five-membered imino-sugars

  摘要：

  An effective and stereo-controlled synthesis of 1,3,4-tris(benzyloxy)-2,5-diiodopentane starting from 2,3,5-tris(benzyloxy)pentane-1,4-diol was reported. Synthesis was improved to get the diiodide compound instead of forming the ring-closure product (benzyloxylated tetrahydrofuran). From the diiodide intermediate, the five-membered aza-sugar was synthesized with high yield. Crown Copyright (C) 2013 Published by Elsevier Ltd. All rights reserved.
