Abstract
In a tris(pentafluorophenyl)borane [B(C6F5)3]‐catalyzed reaction of alkenes with cyanogen halides (XCN), BrCN proceeds in a cyanation/bromination manner, in which a cationic CN character is realized. The ...
G-quadruplexes (G4s) regulate various biological processes in cells. However, cellular imaging of dynamically forming G4s in biomolecular condensates using small molecules has been poorly investigated. Herein, we present a fluorescent light-up pro...

The direct approach: A new high-throughput screening system for analyzing the asymmetric induction in catalytic enantioselective synthesis couples solid-phase reactions with a circular dichroism detection system (see picture). Thus, direct monitor...
A catalytic allyl-transfer reaction from tertiary homoallylic alcohols to aldehydes was achieved using dibutyltin oxide as a catalyst in toluene under reflux conditions. Various secondary homoallylic alcohols were prepared in high yield (up to 99%...

Asymmetric protonation of lithium enolates was examined using commercially available amino acid derivatives as chiral proton sources. Among the amino acid derivatives tested, N beta-L-aspartyl-L-phenylalanine methyl ester was found to cause signif...
