摘要
The spiro concept for chiral ligand design represents an important contribution to the area of asymmetric catalysis. Due to the considerable difficulties in the construction of enantiopure all-carbon spiro backbones, the development of catalytic asymmetric synthesis of chiral spiro structures via short steps is highly valuable. Herein we present our studies on the catalytic asymmetric synthesis of aromatic spiroketals and the corresponding diphos- phine (SKP) ligands.
