  Synthesis of a divalent glycoside of an α-galactosyl disaccharide epitope involved in the hyperacute rejection of xenotransplantation

  摘要：

  3,6-Dioxaoct-1,8-diyl di-(3-O-alpha -D-galactopyranosyl-beta -D-galactopyranoside) was synthesized for use in research on hyperacute rejection of xeno transplantation. The trichloroacetate method was successfully applied to form stereoselectively the a-D-galactosyl linkage under mild reaction conditions and a simple procedure. The divalent O-glycoside was formed from the corresponding trichloroacetimidate in one step with reasonable yield. (C) 2001 Elsevier Science Ltd. All rights reserved.
