Chelation‐Assisted Metal‐Catalyzed Ligation and Cleavage Reactions for Chemical Biology

European Journal of Organic Chemistry, Volume 29, Issue 39, 22 October 2026.
Chelation‐assisted transition metal catalysis has emerged as a promising complement to bioorthogonal click chemistry for studying biological processes. By pre‐organizing catalytic metal centers, designed coordinating substrates enhance reactivity and biocompatibility, enabling site‐selective ligation and decaging reactions in complex biological media ...

1, 3-Dipolar Cycloaddition of Diazomethane with Carbon-Carbon Unsaturated Systems Involving Nitrofuran Ring

Journal of Synthetic Organic Chemistry, Japan, 1968
1, 3-Dipolar cycloaddition reaction of diazomethane with 5-nitro-2-furylacrylic acid gave 4- (5'-nitro-2'-furyl) -3-carbomethoxypyrazoline (3), mp 184485°C, in 80% yield. A similar reaction with 5-nitro-2-furylpropiolic acid afforded the corresponding isomeric mixture of the 2-pyrazole derivatives in 25% yield. (1) was refluxed in toluene to afford 2- (
