Abstract
![]()
A Pd-catalyzed method based on the use of a molecular
tether is
described for olefin difunctionalization. Enabled by an easily introduced
trifluoroacetaldehyde-derived tether, a simultaneous introduction
of oxygen and nitrogen heteroatoms across unsaturated carbon–carbon
bonds was achieved under oxidative conditions, most probably via high-valent
Pd intermediates. Good yields and high diastereoselectivity were obtained
with aryl-substituted alkenes, whereas nonterminal alkyl-substituted
olefins gave aza-Heck products. Tether cleavage under mild conditions
provided fast access to functionalized β-amino alcohols.

Abstract
![]()
We report an enantioselective
palladium-catalyzed trans-hydroalkoxylation of propargylic
amines with a trifluoroacetaldehyde-derived
tether to build chiral oxazolidines. Diastereoselective hydrogenation
using a heterogeneous palladium catalyst then gave access to protected
benzylic amino alcohols in 45–87% yields and 84–94%
ee values. Hydroalkoxylation of the alkynes required a catalytic amount
of aryl iodide, highlighting the counterintuitive key role played
by a putative Pd(II)/ArI oxidative addition complex to promote oxypalladation/protodemetalation.

Abstract
The widespread use of phosphine ligand libraries is frequently hampered by the challenges associated with their modular preparation. Here, we report a protocol that appends arenes to arylphosphines to access a series of biaryl monophosphines via rhodium-catalyzed P(III)-directed ortho C-H activation, enabling unprecedented one-fold, two-fold, and three-fold direct arylation. Our experimental and theoretical findings reveal a mechanism involving oxidative addition of aryl bromides to the Rh catalyst, further ortho C-H metalation via a four-membered cyclometalated ring. Given the ready availability of substrates, our approach opens the door to developing more general methods for the construction of phosphine ligands.

Abstract
Five-carbon (C5) structural units are the fundamental building blocks of many natural products. An unprecedented palladium-catalyzed three-component dehydrogenative cascade coupling of indoles, 2-methylbut-2-ene, and carboxylic acids has been developed. The approach enables the straightforward introduction of a C3'-bonded five-carbon structural unit with a tertiary alcohol quaternary carbon center into indoles. The protocol employs 2-methylbut-2-ene as the C5 source and is featured by a broad substrate scope, atom and step economies, and high chemo- and regioselectivies.

Abstract
We report a copper-catalyzed aminoheteroarylation of unactivated alkenes to access valuable heteroarylethylamine motif. The developed reaction features a copper-catalyzed intermolecular electrophilic amination of the alkenes followed by a migratory heteroarylation. The method applies on alcohol-, amide-, and ether-containing alkenes, overcoming the common requirement of a hydroxyl motif in previous migratory difunctionalization reactions. This reaction is effective for the introduction of diverse aliphatic amines and has good functional group tolerance, which is particularly useful for richly functionalized heteroarenes. This migration-involved reaction was found well suited as a powerful ring expansion approach for the construction of medium-sized rings that are in great demand in medicinal chemistry.

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.

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
1,2-Amino alcohols and α-aminocarbonyls are frequently found in natural products, drugs, chiral auxiliaries, and catalysts. This work reports a new method for the palladium-catalyzed oxyalkynylation and oxyarylation of propargylic amines. The reaction is perfectly regioselective based on the in situ introduction of a hemiacetal tether derived from trifluoroacetaldehyde. cis-Selective carbo-oxygenation was achieved for terminal alkynes, whereas internal alkynes gave trans-carbo-oxygenation products. The obtained enol ethers could be easily transformed into 1,2-amino alcohols or α-amino ketones using hydrogenation or hydrolysis, respectively.
