Synthesis of Sulfur Heterocycles by Palladium‐Catalyzed Cyclization

European Journal of Organic Chemistry, EarlyView.
In spite of the well‐known palladium thiophilicity, sulfur‐containing acyclic substrates may efficiently undergo several different kinds of palladium‐catalyzed cyclization processes leading to highly important sulfur heterocycles in one synthetic step. Advances in this challenging and stimulating field of research are presented in this review.

Transfer Hydrogenation of Organic Azides to Amines by Ammonia Borane Complex Under Mild Conditions Catalyzed by Reusable Au Nanoparticles

European Journal of Organic Chemistry, EarlyView.
Organic azides are readily reduced to amines under mild conditions by ammonia borane complex, catalyzed by a low loading level of reusable Au nanoparticles supported on TiO2. We present the first protocol for the chemoselective reduction of organic azides to amines by ammonia borane complex. In the presence of a low catalytic amount of Au nanoparticles

Synthesis of a Carbon‐Linked Acyldepsipeptide Derivative

European Journal of Organic Chemistry, EarlyView.
The synthesis of a methylene‐linked acyldepsipeptide (ADEP) is reported. Success relied upon an improve method to generate a versatile vinyl glycine methyl ester synthon and a rationally optimized Grubb’s metathesis. NMR and in silico studies revealed an unusual trans–trans proline orientation for this new unnatural ADEP analog, advancing the ...

Catalytic Hydrogenation of Lignin‐Derived Aromatics With Rhodium Oxide in Water

European Journal of Organic Chemistry, EarlyView.
The easily available, easy‐to‐handle rhodium(III) oxide, Rh2O3, is shown to be a competent catalyst for arene hydrogenation, including chemoselective reduction of α,β‐unsaturated aryl ketones. Catalytic arene hydrogenation offers a direct pathway to saturated carbocycles. It can also be exploited to upgrade lignin‐derived aromatics.

A Sustainable Borrowing Hydrogen Strategy in Natural Deep Eutectic Solvents for the N‐Alkylation of Amines From Alcohols

European Journal of Organic Chemistry, EarlyView.
A sustainable, ligand‐free Pd‐catalyzed borrowing hydrogen protocol in a biodegradable hydrophobic natural deep eutectic solvent (NADES) (thymol/DL‐menthol) enables the N‐alkylation of primary amines with benzylic alcohols under mild, aerobic conditions, allowing efficient reuse of both catalyst and solvent for seven consecutive cycles. The hydrophobic
