| Outline of Final Research Achievements |
In organic synthesis, environmentally benign process has been pursued with no use of toxic materials and non precious metals. In this research, optically active 1,2-diols, which can be used as a starting materials for pharmaceutical and functional materials, can be synthesized by use of osmium salts. We examined asymmetric catalytic reaction with terminal alkenes and N,N,N-ligands. Using some of iron complexes and nitrogen ligands has been tried to obtain a small amount of epoxides and diol. On the other hand, the reaction through diboration followed by oxidation giving diols using chiral rhodium catalysts. Bis(oxazolnyl)phenyl-rhodium complex promoted successfully formation of diols from alkenes. In addition, 3-amino-1,2-diols were synthesized with the same Rh catalysts by using amido-, imide-, and carbamate-alkenes as substrates. Moreover, 1,2-disubstituted alkenes was tried by diboration to give the corresponding diols in good yields.
