  Stereoselective synthesis of benzyl-protected β-galactosides by propionitrile-mediated glycosylation

  摘要：

  beta-Selective galactosylation was studied using a series of 2-O-benzylated phenyl 1-thio-galactosides and glycosyl acceptors in propionitrile with BSP-TTBP-Tf2O. The glycosylation enabled us to synthesize useful precursors of N-acetyllactosamine and core 1 O-glycoserine derivatives in a highly convergent manner. (c) 2008 Elsevier Ltd. All rights reserved.
