| Research Abstract |
Utilizing the unique property of sugar derivatives, which conformation were locked into the axial-rich conformation, we developed (1) synthesis of ellagitannins and (2) stereoselective glycosylation reactions. In the research for (1), new synthetic routes for the axial-rich ellagitannins were developed to increase the lead in the aria of ellagitannin synthesis. For (2), highly α-selective glycosylations were developed by applying the sugars locked to the axial-rich conformations.
