Catalytic asymmetrization of racemic dicyclopentadiene derivatives by using chiral copper(II) catalyst
Treatment of racemic dicyclopentadiene derivatives with tert-butyl peroxybenzoate in the presence of a catalytic amount of Cu(II)-tris- or bis-(oxazoline) complex directly gave optically active benzoyloxylated dicyclopentadiene derivatives, useful building blocks bearing multiple asymmetric centers, in a highly enantioselective manner (up to 87% ee).
