  The First Polymer-Assisted Solution-Phase Synthesis of Deoxyglycosides

  摘要：

  [GRAPHICS]A glycosylation protocol for the synthesis of 2-deoxyglycosides has been developed which is based on the use of polymer-bound reagents. Glycals are transformed into 2-iodoglycosyl acetates using polymer-bound bis(acetoxy)iodate(1) complex (1). Activation of the anomeric center is achieved by employing polymer-bound silyl triflate (2). In the presence of different glycosyl acceptors, 2-deoxy-2-iodoglycosides are generated in very good yields. Furthermore, it is shown that this method can be embedded in multistep sequences toward glycosylated testosterone and rhodinosyl-olivosyl-olivoside.

• Iodine(III)-Initiated Bromoacetoxylation of Olefins

  日期：1998.2

  A new and mild method for the bromoacetoxylation of olefins is presented, which is initiated by iodine(III). α-Acetoxy bromides 6-11 are generated from olefins 5 in the presence of tetraethylammonium bromide (1) and (diacetoxyiodo)benzene (2). The 1,2-addition to carbohydrate-derived enol ethers results in 2-deoxy-2-bromo-pyranosyl acetates which are versatile glycosyl donors for the synthesis of 2'-deoxy-2'-bromo glycosides 16.

  提出了一种新的温和方法，用于烯烃的溴乙酸酯化反应，该反应由碘(III)启动。在四乙基溴化铵(1)和(二乙酸氧碘)苯(2)的存在下，从烯烃5生成α-乙氧基溴化物6-11。对碳水化合物衍生的烯醇醚进行1,2-加成，得到2-脱氧-2-溴-吡喃糖乙酸酯，这些化合物是合成2'-脱氧-2'-溴糖苷16的多功能糖苷供体。
