  Enantioselective synthesis of Boc-protected norfuranomycins

  摘要：

  Garner's aldehyde is a suitable precursor for the synthesis of both isomers of Boc-protected epi-norfuranomycin. We demonstrate the utility of trisyl chloride as an effective leaving group in the dihydrofuran formation step. We also show that TEMPO/BAIB is an effective oxidant for a-amino alcohols avoiding epimerization of the labile a-proton of the product aldehyde. (C) 2011 Elsevier Ltd. All rights reserved.
