Outline of Final Research Achievements

The site-selective modification of a polyol such a carbohydrate bearing multiple hydroxyl groups without protection groups is still challenging in synthetic organic chemistry. The sequential protection-deprotection steps on the hydroxyl groups require lengthy synthetic steps for accessing the functionalized-polyol compound, hence resulting in inefficient synthetic processes. To overcome this problematic issue in the poll modification, we in this study established a novel catalyst-controlled modification of polyols with the benzoxaborole catalyst. This methodology enables a straightforward synthesis of polyol derivatives including oligo saccharide and antibiotics
