Transition-Metal-Catalyzed Three-Component Difunctionalizations of Alkenes.
TL;DR: This Focus Review highlights recent advances in transition-metal catalysis in the difunctionalization of alkenes to facilitate the construction of a wide range of functional molecules with high atom- and step-economic efficiency.
Journal ArticleDOI
Manganese(I)-Catalyzed Regioselective C-H Allenylation: Direct Access to 2-Allenylindoles.
TL;DR: Mechanistic investigations revealed that the precoordination of the oxygen atom to the manganese center as well as the congested tertiary carbon atom in the propargylic carbonates play a crucial role in this transformation.
Journal ArticleDOI
Intermolecular [2+2] Reaction of N‐Allenylsulfonamides with Vinylarenes: Enantioselective Gold(I)‐Catalyzed Synthesis of Cyclobutane Derivatives
TL;DR: The first asymmetric gold-catalyzed intermolecular allenene[2+2] cycloaddition is reported, which would provide a yet unknown and straightforward entry into optically active cyclobutanes from readily available allenamides and alkenes, in a sole synthetic operation.
Journal ArticleDOI
Manganese-Catalyzed C−H Functionalizations: Hydroarylations and Alkenylations Involving an Unexpected Heteroaryl Shift
TL;DR: A hydroarylation/cyclization cascade involving an unexpected C-N bond cleavage and aryl shift has been developed, which provides a new synthetic approach to substituted pyrroloindolones.

Gold-catalyzed nucleophilic cyclization of functionalized allenes: a powerful access to carbo- and heterocycles.
Norbert Krause,Christian Winter +1 more
TL;DR: This account comprises gold-catalyzed cyclization reactions of allenes by attack of carbon or heteroatom nucleophiles, which are particularly well suited for the selective activation of allene in the presence of other reactive functionalities.
Journal ArticleDOI
Reactions of electron-deficient alkynes and allenes under phosphine catalysis.
TL;DR: This study illuminates the unusual phenomena and shows how understanding of the central problem to generate a 1,3-dipole from alkynoates or allenoates by interaction with various phosphines allows control of the reaction.
Journal ArticleDOI
Nucleophilic Phosphine Organocatalysis
Joey L. Methot,William R. Roush +1 more
TL;DR: In this article, a mini-review presents recent advances in nucleophilic phosphine organocatalysis for carbon-carbon bond formation, showing that the accessibility of chiral phosphines has rendered several of these transformations enantioselective and has made possible the kinetic resolution of racemic secondary alcohols by phosphine-catalyzed acylation.
Journal ArticleDOI
A powerful chiral counterion strategy for asymmetric transition metal catalysis.
TL;DR: It is shown that the chiral counterion can be combined additively with chiral ligands to enable an asymmetric transformation that cannot be achieved by either method alone.
