Push–Pull Ynamines and Push–Pull Ynamides: Synthesis, Structure, Reactivity, and Application

European Journal of Organic Chemistry, EarlyView.
Push–pull ynamines and push–pull ynamides, which carry an EWG and an amino or amido group as EDG, are highly interesting classes of EDG‐EWG alkynes that have been intensively studied due to their exceptional reactivity. In this review, the synthesis, structure, reactivity, and application of push–pull ynamines, push–pull ynecarbamates, push–pull ...

Mechanochemical Hydrodeoxygenations

European Journal of Organic Chemistry, EarlyView.
A silver‐catalyzed mechanochemical hydrodeoxygenation with triethylsilane as reductant allows to convert ketones to the corresponding methylene derivatives in good yields after a short reaction time. Selected examples show that also alcohols, ethers, and sulfoxides can react. In this work, a mechanochemical hydrodeoxygenation (HDO) was developed. Using

Design and Synthesis of Lactose‐Derived Ligands and Their Application in Asymmetric Friedel–Crafts Alkylation

European Journal of Organic Chemistry, EarlyView.
This work describes the synthesis of lactose‐ and glucose‐derived chiral ligands and their application in the catalytic enantioselective Friedel–Crafts alkylation of indole with a series of trans‐β‐nitrostyrenes. The optimal ligand was an acetate protected, lactose‐derived pyridyl imine and its zinc complex afforded ees up to 93% and yields up to 93 ...

Photochemical Decatungstate‐Catalyzed Hydroacylation of Maleimides

European Journal of Organic Chemistry, EarlyView.
A photocatalytic protocol to access substituted succinimides via tetra‐n‐butylammonium decatungstate photocatalysis is reported. This direct radical‐driven hydroacylation of a variety of N‐substituted maleimides shows tolerance to various aldehydes (or alkanes), affording differentially substituted succinimides in high yields. Succinimides constitute a

Nickel‐Catalyzed Three‐Component Coupling Reactions of Iodobenzenes, an Isocyanide, and a Disilathiane: Access to Cyclic Thioimidates and Secondary Thioamides

European Journal of Organic Chemistry, EarlyView.
The one‐pot synthesis of 3‐benzylidenbenzo[c]thiophen‐1‐amines was achieved through the nickel‐catalyzed three‐component coupling reaction of 1‐ethynyl‐2‐iodobenzenes, tert‐butyl isocyanide, and hexamethyldisilathiane. This procedure is applicable to the preparation of secondary thioamides using aryl iodides.
