  名称：

  d-Ribofuranosylenamine: a versatile starting material for preparing azasugar thioglycosides and building blocks for thioureylene-di-nucleosides

  摘要：

  Six-membered azasugar thioglycosides (piperidines) are prepared from a beta-D-ribofuranosylenamine, with a 1,5-anhydro derivative being the key intermediate. The alpha-anomer of the same D-ribofuranosylenamine is transformed into a 5-deoxy-5-isothiocyanato derivative, useful for preparing D-ribosylamino derivatives with a non-ionic thiourea bridge, isosteric of the phosphate bridge. The prepared thioureas are potential building blocks for the synthesis of thioureylene-di-nucleosides. (C) 2004 Elsevier Ltd. All rights reserved.
