[(Indenyl)Ru(biphop-F)]+: A Lewis Acid Catalyst That Controls both the Diene and the Dienophile Facial Selectivity in Diels-Alder Reactions
Autor: Valérie Alezra, E. Peter Kündig, Gérald Bernardinelli, Christophe M. Saudan, Florian Viton
Publikováno v: Angewandte Chemie. 113:4613-4617
The indenyl roof over the chiral Lewis acid catalyst site of [(indenyl)Ru((S,S)-biphop-F)]+ (see picture) gives rise not only to high enantioselectivities in Diels-Alder reactions between enals and cyclopentadiene but also affects the endo/exo diaste

Chiral Cyclopentadienyl-Iron and -Ruthenium Lewis Acids Containing the Electron-Poor BIPHOP-F Ligand: a Comparison as Catalysts in an Asymmetric Diels-Alder Reaction
Autor: Christophe M. Saudan, Florian Viton, E. Peter Kündig
Publikováno v: Advanced Synthesis & Catalysis. 343:51-56
Chiral iron and ruthenium Lewis acids: analogies and differences between the catalysts and the role of the anion in catalytic Diels-Alder reaction. In short: Fe catalysts are faster but Ru analogues are more stable and can be recovered quantitatively

A Stable and Recoverable Chiral Ru Lewis Acid: Synthesis, Asymmetric Diels–Alder Catalysis and Structure of the Lewis Acid Methacrolein Complex
Autor: Gérald Bernardinelli, E. Peter Kündig, Christophe M. Saudan
Publikováno v: Angewandte Chemie International Edition. 38:1219-1223
Ease of generation, stablity in solution at ambient temperature, high enantioselectivity in Diels-Alder reactions, efficient catalyst recovery, and large rate differences on variation of the anion are all characteristics of the new Ru Lewis acid [CpR
