Enantiomerically Enriched Aziridine‐2‐carboxylates via Copper‐Catalyzed Reductive Kinetic Resolution of 2H‐Azirines

Angewandte Chemie International Edition, Accepted Article.
We present the first reductive kinetic resolution of racemic 2H‐azirines to prepare optically enriched N‐H aziridine‐2‐carboxylates, which are bench stable and easily diversifiable building blocks, concomitantly with the corresponding enantiomerically enriched 2H‐azirines. The N‐H aziridines were obtained with excellent diastereoselectivity (>20:1) and

Red‐Light‐Mediated Generation of Radicals: Applications in Organic Synthesis, Small‐Molecule Activation, Polymerization, and Bio‐Related Fields

Angewandte Chemie International Edition, Accepted Article.
The field of visible light‐mediated photochemistry has experienced significant growth, leading to the development of a wide array of methodologies in synthetic organic chemistry. In particular, photocatalysis by using long‐wavelength light such as red and near‐infrared (NIR) light has garnered substantial attention recently.

Photocatalytic Generation of a Ground‐State Electron Donor Through Water Activation

Angewandte Chemie International Edition, EarlyView.
This study presents catalytically generated phosphine oxide radical anions, derived from commercial phosphines and water as potent single‐electron reductants capable of reducing electron‐rich aryl chlorides at potentials as low as −3.3 V (vs. SCE). Cyclic voltammetry studies and DFT calculations offer insights into these P‐based ground‐state electron ...
