Research Grants & Projects

 
Efficient Synthesis of Important Bioactive Medium-Size Polycyclic Natural Products
Project Year: Jun 2015 - Mar 2020
Research on Asymmetric Catalysis Based on Design and Synthesis of New Chiral Pincer-Type NHC Ligand
Project Year: Apr 2014 - Mar 2016
We have established a synthetic method for the bisoxazoline-NHC-Ag(I) complex via concomitant formation of oxazolines and NHC using silver oxide, and the bisoxazoline-NHC-Ag(I) complex were converted to the corresponding pincer-type NHC-metal comp...
Catalytic Asymmetric Reactions of Alkenes Activated by Two Electron-Withdrawing Groups and Their Applications to Efficient Enantioselective Total Syntheses
Project Year: Apr 2013 - Mar 2016
A synthetic method of alpha-alkylidene-beta-oxo imides and their catalytic asymmetric reactions ([4+2] and [2+2]cycloadditions, Mukaiyama-Michael reaction, Hosomi-Sakurai-Michael reaction, and Friedel-Crafts reaction) have been successfully develo...
Research on the design and synthesis of chiral NHC pincer ligands and their utility for asymmetric catalysis
Project Year: Apr 2011 - Mar 2013
A new chiral N-heterocyclic carbene (NHC) pincer-type ligand was synthesized. Its cationic platinum complex catalyzed an enantioselective cycloisomerization of a 1,5-ene-yne. A new preparation method of imidazolinium salts from the corresponding t...
Synthetic Studies on Bioactive Natural Products utilizing Integrated
Project Year: Apr 2009 - Mar 2014
