| Outline of Final Research Achievements |
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 complexes. The NHC-Cr(III) complex showed no catalytic activity, but the dicationic NHC-Pt(II) complex catalyzed cycloisomerization of a 1,5-ene-yne albeit with low enantioselectivity. We have successfully synthesized a binaphthyl-fused imidazolylidene-AuCl complex and have found that the corresponding cationic complex catalyzes enantioselective cyclization of an ene-yne to afford quantitatively the product with 78% ee. Synthesis of the corresponding pincer-type binaphthyl-fused NHC ligands is now investigation.
