| Research Abstract |
Asymmetric intramolecular conjugate addition reaction and intramolecular alkylation reaction via planar chiral enolates were investigated in detail. As a result of various exanimation of reaction conditions, it was found that electron-withdrawing groups in the part of Michael acceptor played an important role in yield and optical purity of products in asymmetric conjugate addition reaction. On the other hand, the substituents on aromatic ring which are adjacent to enolate and electrophilic residue were found to affect yield and optical purity of products in asymmetric intramolecular alkylation reaction. These reactions would be used in the total syntheses of bioactive natural products as a key step.
