  A short and highly stereoselective synthesis of α-(2-aminothiazolyl)-C-nucleosides

  摘要：

  A short route to novel alpha-(2-aminothiazolyl)-C-nucleosides has been developed. The key step was the high diastereoselective reduction of the hemiacetal intermediates using L-Selectride, which afforded the corresponding R-diols in quantitative yields. These diols were converted, after C4-C1 ring closure and protecting groups cleavage, to their corresponding free alpha-C-nucleosides. (C) 2003 Elsevier Science Ltd. All rights reserved.
