  Synthesis of two trisaccharides related to the hepatoprotective phenylethanoids leonoside E and F isolated from Leonurus japonicus Houtt

  摘要：

  The chemical synthesis of two trisaccharides related to leonoside E and F is reported. The target oligosaccharides were prepared in the form of their p-methoxyphenyl glycosides using a common disaccharide acceptor. All reaction steps were high yielding (>80%) and the stereoselective glycosylations were achieved by activation of the thioglycoside donors using N-iodosuccinimide in the presence of La(OTf)(3).
