❶ Utilization of N－X bonds in the synthesis of N-heterocycles

Simple nitrogen-containing heterocycles could be constructed from carbon-carbon double bond (including fulleren) as carbon resources.

Acc. Chem. Res. 2009, 42, 1172.

❷ Application of carbon dioxide to organic synthesis

Carbon dioxide fixation to unsaturated alcohols could be realized under extremely mild conditions by using tert-BuOI.

Angew. Chem. Int. Ed. 2010, 49, 1309.

Haloamidation of olefins induced by carbon dioxide was developed.

Org. Lett. 2006, 8, 967.　Org. Bio.mol. Chem. 2010, 8, 1424.

❸ Application of water/silica system to organic synthesis

Organic reactions on silica in water were successfully achieved by utilizing hydrophobic interaction.
