Facile, one-pot synthesis was developed for several β(1→2)-, β(1→3)- or β(1→4)-linked disaccharides from fully unprotected methyl hexopyranosides according to the molecular recognition by arylboronic acids. The methodology was successfully applied to facile, short step assembly of the trisaccharide fragment of type II arabinogalactan.
根据芳基硼酸的分子识别,从完全未保护的甲基己基吡喃糖苷开发了几种简单的一锅合成方法,用于几种β(1→2)-,β(1→3)-或β(1→4)连接的二糖。该方法已成功应用于II型阿拉伯半乳聚糖三糖片段的简便,短步组装。
