A unique approach to the synthesis of a dengue vaccine and the novel tetrasaccharide that results
摘要:
An approach to the development of a dengue vaccine by synthesizing the hexasaccharide epitope on the viral surface is examined. The stereochemical and structural challenges include the synthesis of a beta-mannoside bond. Synthesis of this bond is approached via a trisaccharide analogue portion of the epitope. A novel tetrasaccharide with a mannose-mannose anomeric linkage results in the Course of the synthetic attempts. (C) 2009 Elsevier Ltd. All rights reserved.
