  Electrochemical synthesis of glycoconjugates from activated sterol derivatives

  摘要：

  Several derivatives of cholesterol and other 3 beta-hydroxy-Delta(5)-steroids were prepared and tested as sterol donors in electrochemical reactions with sugar alcohols. The reactions afforded glycoconjugates with sugar linked to a steroid moiety by an ether bond. Readily available sterol diphenylphosphates yielding up to 54% of the desired glycoconjugate were found to be the best sterol donors. (C) 2014 Elsevier Inc. All rights reserved.

  electrochemical synthesis of glycoconjugates is presented. Thioether derivatives of cholesterol and other sterols were subjected to anodic oxidation in the presence of a sugar alcohol affording glycoconjugates with the sugar linked to a steroid moiety by an ether bond. The isomeric 6β-3α,5α-cyclo-steroidal thioethers proved to be better sterol donors than the normal 3β-Δ5-steroidal thioethers.

  对于糖缀合物的电化学合成一个新的协议，提出。胆固醇和其它甾醇的硫醚衍生物的糖醇，得到与通过醚键连接至类固醇部分的糖的糖缀合物的存在下进行阳极氧化。同分异构的6β-3α，5α-环-steroidal硫醚被证明是更好的固醇捐助者比正常3β-Δ 5 -steroidal硫醚。
