Azetidines are prominent structural scaffolds in bioactive molecules, medicinal chemistry,
and ligand design for transition metals. However, state-of-the-art methods cannot be applied …

Herein we disclose a strategy to promote the hydrocarboxylation of unactivated alkenes
using photochemical activation of formate salts. We illustrate that an alternative initiation …

We report a highly enantioselective radical-based hydroamination of enol esters with
sulfonamides jointly catalyzed by an Ir photocatalyst, Brønsted base, and tetrapeptide thiol …

Noncovalent interactions between a lone pair of electrons and π systems can be
categorized into two types based on the nature of π systems. Lone pair− π (C═ O) …

A simple and general method for anti-selective hydrosulfonylation of unactivated alkynes
with sulfonyl chlorides in the presence of a catalytic amount of phenanthroline-based Lewis …

Through the lens of organocatalysis and phase transfer catalysis, we will examine the key
components to calculate or predict catalysis-performance metrics, such as turnover …

As a type of elementary organic compounds containing N− N single bond, hydrazone
involved chemical conversions are extremely extensive, but they are mainly limited to N2 …

Enantioenriched pyrrolidines and derivatives are ubiquitous substructures in compounds of
importance to medicinal and biological chemistry. Herein, we report an efficient cobalt …

We recently reported a chiral phosphoric acid (CPA) catalyzed enantioselective
photomediated ring contraction of piperidines and other saturated heterocycles. By …

Fluorescent molecules play a crucial role in biomedicine by facilitating the visualization and
tracking of biological processes with sensitivity and specificity. However, tailoring their …
