- Stereoselective synthesis of new rac-quercitols containing hydroxymethyl groups as glucosidase inhibitors
-
Stereoselective and efficient synthesis of hydroxymethyl-substituted rac-quercitols (13–15) was achieved, starting from cis-furan (Kobayashi, 2008) with photooxygenation reaction, which is readily available by the reduction of cis-phtalic anhydride. α- and β-Glucosidase enzyme activity of the target molecules was evaluated and good inhibitor activity was seen. One- and two-dimensional NMR spectroscopy, IR spectroscopy and X-ray crystallography were utilized in the structure characterization of products.

- Application of oxidative desymmetrization of meso-tetrahydrofurans: Syntheses of functionalized chiral building blocks and of (-)-alloyohimbane
-
Oxidative desymmetrization of oxygen functionalized mesotetrahydrofurans was successfully achieved (up to 87% ee) through (salen)manganese(III) catalyzed enantiotopic selective C-H oxidation. The enantioselective synthesis of (-)-alloyohimbane (12) has also been achieved in a short step by using oxidative desymmetrization of meso-tetrahydrofuran as the key step.
