Concise synthesis of a heptasaccharide antigen found in the cell-wall lipopolysaccharide of Mycobacterium gordonae strain 990

摘要

A straight forward synthesis of a heptasaccharide part of the cell-wall lipopolysaccharide of Mycobacterium gordonae strain 990, known to have antigenicity, has been achieved in excellent yield. Judicious choice of protecting groups in the intermediates played a significant role throughout the synthesis. Most of the intermediate steps furnished satisfactory yield.
