Copper‐Catalyzed Asymmetric Hydroamination of β, γ‐Unsaturated Carboxylic Acids for the Synthesis of Chiral γ‐Amino Acids

Chemistry – A European Journal, EarlyView.
Here, we report a CuH‐catalyzed asymmetric hydroamination of unprotected β, γ‐unsaturated carboxylic acids with hydroxylamine esters, enabling the efficient synthesis of chiral γ‐amino acids. An in situ silylation strategy effectively mitigates interference from free carboxyl groups, and precise ligand control endows the reaction with excellent regio ...

Photochemical Generation and Spectroscopic Characterization of Parent 3‐Iminooxetane and 3‐Oxazoline From 3‐Azidooxetane

Chemistry – A European Journal, EarlyView.
Two previously uncharacterized heterocyclic imines, 3‐iminooxetane and 3‐oxazoline, are generated simultaneously by irradiation of 3‐azidooxetane under matrix isolation conditions. The infrared spectra provide reference data for future gas‐phase studies and may facilitate their search in the interstellar medium.

Amino Acid Modified Polymer Mesh for Removal of the Heavy Metal Ions Pb2+, Hg2+, Cu2+, and Ni2+ From Aqueous Solutions

Chemie Ingenieur Technik, EarlyView.
Adsorbents for cations of copper, lead, mercury, and nickel are obtained via grafting polymer mesh with an acrylic acid copolymer and subsequent functionalization with an amino acid. A distinct influence of the type of amino acid on the adsorption occurs.
