Angewandte Chemie, EarlyView.A nanopore composed of transmembrane peptides and a DNA scaffold that assists peptide assembly was constructed. By employing peptides containing the unnatural amino acid 2‐aminoisobutyric acid (Aib), which promotes loose packing between helices, a large‐diameter nanopore was achieved.

Thermal Stability and Explosive Hazard Assessment of Diazo Compounds and Diazo Transfer Reagents
, 2019 Despite their wide use in academia as metal-carbene precursors, diazo compounds are often avoided in industry owing to concerns over their instability, exothermic decomposition, and potential explosive behavior. The stability of sulfonyl azides and other

Asymmetric formal C–C bond insertion into aldehydes via copper-catalyzed diyne cyclization
Nature Communications, 2023 The formal C–C bond insertion into aldehydes is an attractive methodology for the assembly of homologated carbonyl compounds. However, the homologation of aldehydes has been limited to diazo approach and the enantioselective reaction was rarely developed.
