  Design and synthesis of a heparanase inhibitor with pseudodisaccharide structure

  摘要：

  Aza-analogue of the basic disaccharide unit of heparane sulfate was designed as a potent inhibitor against heparanase produced by solid tumors cell, and synthesized via a coupling reaction of phenyl 2-azide-1-thio-D-glucopyranoside derivatives with a partially protected 1-deoxynojirimycin derived from D-glucose. The azapseudodisaccharide inhibited tumor cell heparanase with IC50 value of 58-63 muM. (C) 2001 Elsevier Science Ltd. All rights reserved.

  RAPID CARBOHYDRATE PROTECTING GROUP MANIPULATIONS ASSISTED BY MICROWAVE DIELECTRIC HEATING

  摘要：

  The protocols for oligosaccharide synthesis are often tedious due to extended synthetic routes and reaction times. We herein describe methods assisted by microwave dielectric heating, which enable very short reaction times and high yields for the introduction and removal of eleven of the most commonly used protecting groups in carbohydrate syntheses. Several examples are reported, where solid supported reagents in combination with microwave dielectric heating have been used. This results in both faster and easier synthesis and purification.

• Approaches to new water-soluble phosphines
  作者：Terence N. Mitchell、Kerstin Heesche-Wagner

  DOI：10.1016/0022-328x(92)85025-r

  日期：1992.9

  Approaches to water-soluble phosphines are described which involve conversion of ethylene glycol derivatives and sugar diacetonides into monoallyl ethers, and hydrophosphorylation of the latter. In the case of the sugars, water-solubility is conferred by a subsequent hydrolysis.

  日期：2003.6.1

  The 1,3-dipolar cycloaddition of sugar ketonitrones is a useful synthetic procedure to build up nitrogenated quaternary centers in terms of scope (substrate, dipolarophile, inter- and intramolecular versions), yield, and regio- and stereoselectivity. The hybrid ONIOM (B3LYP/6-31G(d):AM1) theoretical method followed by single-point energy calculations at the B3LYP/6-31G(d) level adequately perform to

• Allyl, Methallyl, Prenyl, and Methylprenyl Ethers as Protected Alcohols:  Their Selective Cleavage with Diphenyldisulfone under Neutral Conditions
  作者：Dean Marković、Pierre Vogel

  DOI：10.1021/ol049135q

  日期：2004.8.1

  Diphenyldisulfone is a mild and efficient reagent for selective cleavage of methylprenyl (2,3-dimethylbut-2-en-1-yl), prenyl (3-methylbut-2-en1-yl), and methallyl (2-methylallyl) ethers. These reaction conditions are compatible with the presence of other protecting groups such as acetals, acetates, and allyl, benzyl, and TBDMS ethers. Exposure of 2,3-dimethylbut-2-en-1-yl and 3-methylbut-2-en1-yl ethers to diphenyldisulfone
