Synthesis of the tetrasaccharide side chain of the major glycoprotein of the Bacillus anthracis exosporium
摘要:
An alpha-glycoside of the tetrasaccharide sequence beta-Ant-(1 -> 3)-alpha-L-Rhap-(1 -> 3)-alpha-L-Rhap-(1 -> 2)-alpha-L-Rhap whose aglycon allows conjugation to suitable carriers was synthesized. The NMR characteristics of the compound are virtually identical with those of the alpha-anomer of the tetrasaccharide isolated from the major glycoprotein of the Bacillus anthracis exosporium. Thus, the correct structure of the natural product has been proven by chemical synthesis. (c) 2005 Elsevier Ltd. All rights reserved.
