Carbon-13 N.M.R. shifts as a measure of transannular interaction in unsaturated alicyclic systems
, 1984 Through-space transannular interaction between formally non-conjugated methylene and carbonyl n-electrons in conformationally rigid 3,7-disubstituted bicyclo[3.3.1]nonanes (1) has been demonstrated by Senda et al. by comparing the 13C n.m.r. shift values

Advanced Synthesis &Catalysis, Volume 368, Issue 2, January 2026.A rhodium(II)‐catalyzed ring expansion of stereodefined dihydro‐1,3‐thiazines with diazomalonates gives 1,4‐thiazepines via a sulfonium ylide rearrangement. The reaction shows a cis/trans reactivity divergence arising from different metal coordination, as revealed by experiments and density functional theory studies.

A whole cell biocatalyst for double oxidation of cyclooctane
Journal of Industrial Microbiology and Biotechnology, 2016 Abstract A novel whole cell cascade for double oxidation of cyclooctane to cyclooctanone was developed. The one-pot oxidation cascade requires only a minimum of reaction components: resting E. coli cells in aqueous buffered medium (=catalyst), the target substrate and oxygen as environmental friendly oxidant.

Spirocyclic Diamine Scaffolds for Medicinal Chemistry
Helvetica Chimica Acta, Volume 109, Issue 1, January 2026.Here we enumerated 391 spirocyclic diamine drug scaffolds with ring sizes four to eight and found that most of them are unknown. We prepared four novel such spirocycles and discovered a micromolar inhibitor of the M4 muscarinic receptor. ABSTRACT Medicinal chemistry requires the exploration of structurally diverse compound families to expand the ...

Dual‐Fluorophore Labeling for Polymer Blending Differentiation and Visualization
Aggregate, Volume 6, Issue 12, December 2025.This work employs a dual fluorescent labeling strategy to visualize phase separation in polymer blends. Using confocal laser scanning microscopy, distinct phase separation is clearly observed in the absence of a compatibilizer. This phenomenon disappears upon compatibilizer addition, demonstrating the strategy's effectiveness in monitoring blend ...
