Abstract
Ligands containing ferrocene backbones often feature both planar chirality and asymmetric centers, making them attractive options for asymmetric catalysis. Ugi's amine is a ubiquitous ferrocene-based chiral building block that can be functionalized to form a variety of tunable Josiphos ligands; however, few sources lay out the route from start to finish. Starting from ferrocene, we compile a synthetic route to an air- and moisture-stable copper(I)-Josiphos complex via enantiopure Ugi's amine, providing a potential one-stop shop for the synthesis of a wide range of Josiphos ligands.

Abstract
AbstractThis review presents an account of the palladium-catalyzed functionalizations of alkenes and alkynes developed at the Laboratory of Catalysis and Organic Synthesis (LCSO). Starting from the intramolecular oxy- and aminoalkynylation of alkenes, tethered methods were then developed to functionalize allylic amines and alcohols, as well as propargylic amines. Finally, a new dynamic kinetic asymmetric transformation was developed based on the use of a ‘one-arm’ Trost-type ligand, giving access to enantiopure amino alcohols. Each section is a personal account by the researcher(s) who performed the work.1 Introduction,2 Oxy- and Aminoalkynylation of Olefins,3 In Situ Tethering Strategies for the Synthesis of Vicinal Amino Alcohols and Diamines,4 Carboamination of Allylic Alcohols,5 Carbooxygenation of Propargylic Amines,6 Enantioselective Carboetherification/Hydrogenation via a Catalytically Formed Chiral Auxiliary,7 Conclusion

Abstract
![]()
Chiral auxiliaries
and asymmetric catalysis are the workhorses
of enantioselective transformations, but they still remain limited
in terms of either efficiency or generality. Herein, we present an
alternative strategy for controlling the stereoselectivity of chemical
reactions. Asymmetric catalysis is used to install a transient chiral
auxiliary starting from achiral precursors, which then directs diastereoselective
reactions. We apply this strategy to a palladium-catalyzed carboetherification/hydrogenation
sequence on propargylic amines, providing fast access to enantioenriched
chiral amino alcohols, important building blocks for medicinal chemistry
and drug discovery. All stereoisomers of the product could be accessed
by the choice of ligand and substituent on the propargylic amine,
leading to a stereodivergent process.

Abstract
Based on the asymmetric copper-catalyzed 1,2-addition of Grignard reagents to ketones, (R,R,R)-γ-tocopherol has been synthesized in 36 % yield over 12 steps (longest linear sequence). The chiral center in the chroman ring was constructed with 73 % ee by the 1,2-addition of a phytol-derived Grignard reagent to an α-bromo enone prepared from 2,3-dimethylquinone.
