The photophysical properties and photocatalysis of tris(pentafluorophenyl)borane [B(C6F5)3], known as a strong Lewis acid, were revealed. The excited-state B(C6F5)3 exerts single-electron oxidation capability with an oxidation potential (Ered* = 2.02

Allylic C–H activation of enol silyl ethers via one-electron oxidation is usually accompanied by undesired desilylation. Here, under hybrid photoredox and Brønsted base catalysis, the authors show the mild functionalization of enol silyl ethers, p

Inhibition of transmembrane serine protease 2 (TMPRSS2) is expected to block the spike protein-mediated fusion of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Nafamostat, a potent TMPRSS2 inhibitor as well as a candidate for anti-SAR

For reactions producing numerous chiral centres, accessing all potential stereoisomers is synthetically appealing but difficult. Here, the authors report a stereodivergent 1,6-addition of azlactones where minimal changes to the catalyst structure swi

A highly diastereo- and enantioselective Mannich-type reaction of 3-aryloxindoles with N-Boc aldimines was achieved under the catalysis of axially chiral ammonium betaines. This catalytic method provides a new tool for the construction of consecutive
