Structural and mutational analysis of Methanosarcina mazei prenylated FMN synthase reveals the basis of its unique prenyl donor substrate specificity

The FEBS Journal, EarlyView.
Some prenylated flavin mononucleotide (prFMN) synthases exceptionally prefer dimethylallyl phosphate (DMAP) over dimethylallyl diphosphate (DMAPP), which is a common prenyl donor substrate for many prenyltransferases. Structural and mutagenic analyses of Methanosarcina mazei prFMN synthase, which prefers DMAP but can also accept DMAPP, elucidated its ...

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- (

Recent Applications of Propylene Carbonate as a Solvent in Sustainable Organic Synthesis

ChemSusChem, Volume 19, Issue 17, 14 September 2026.
This review evaluates propylene carbonate (PC) as a non‐toxic green solvent in organic synthesis, highlighting its performance in key reactions including cross‐couplings, asymmetric hydrogenations, peptide synthesis and biocatalysis. Across these processes, PC delivers yields comparable to conventional and alternative green solvents.

Alkoxyallenes in Modern Synthesis: Reactivity, Catalysis, and Complexity Generation

Advanced Synthesis &Catalysis, Volume 368, Issue 17, 1 September 2026.
The last decade has witnessed a remarkable transformation in alkoxyallene chemistry. Although historically employed as synthetic equivalents of acrolein or as versatile 3C synthons, alkoxyallenes are now increasingly recognized as highly adaptable platforms for synthetic design.

The Jekyll and Hyde Nature of Tetrazoles in Polymer Science: From Intrinsic Electronic Duality to Programmable Macromolecular Function

Angewandte Chemie International Edition, Volume 65, Issue 36, 1 September 2026.
Tetrazoles are reframed as substitution‐programmable heterocycles rather than static functional groups in polymer chemistry. By linking electronic identity to synthetic strategy and polymer architecture, this mini‐review establishes a design framework for translating tetrazole duality into predictable macromolecular function.

1,3‐Dipolar Cycloaddition of Nitroalkanes as a Tool of DOS/LOS‐Like Strategy for the Synthesis of Isoxazoles and Isoxazolines

ChemistryEurope, Volume 4, Issue 9, September 2026.
A broadly applicable synthetic platform based on a DOS/LOS‐like strategy is implemented for the case of sp3‐enriched isoxazole/isoxazoline building blocks. The method is based on a [3+2] cycloaddition of nitroalkanes and various alkenes or alkynes. The utility of the proposed approach is illustrated by the discovery of JAK2‐selective inhibitors.
