Ir-Catalyzed Atroposelective Desymmetrization of Heterobiaryls: Hydroarylation of Vinyl Ethers and Bicycloalkenes
(American Chemical Society, 2020)
A highly regio-, diastereo-, and enantioselective, scalable Ir-catalyzed hydroarylation of electron-rich acyclic and tensioned cyclic olefins with heterobiaryls is described. The reaction of acyclic vinyl ethers, dihydrofuran, ...

AuI-Catalyzed Haloalkynylation of Alkenes
(Wiley-Blackwell, 2020)
The formal insertion of alkenes into aromatic chloro- and bromoalkynes takes place under cationic gold catalysis. This haloalkynylation reaction can be performed with cyclic, gem-disubstituted and monosubstituted alkenes, ...

AuI-Catalyzed Hydroalkynylation of Haloalkynes
(American Chemical Society, 2020)
The AuI-catalyzed reaction between terminal alkynes and aromatic haloalkynes proceeds through divergent pathways depending on the nature of the catalyst counteranion. Thus, cationic complexes containing strongly basic NHC ...

Catalytic Enantioselective Synthesis of a-aryl a-hydrazino Esters and Amides
(Royal Society of Chemistry, 2020)
Catalysts generated by combinations of Pd(TFA)2and pyridine-hydrazone ligands have allowed the asymmetric 1,2-addition of aryl boronic acids toN-carbamoyl (Cbz and Fmoc) protected glyoxylate-derived hydrazones, yielding ...
