1,2‐Diazetidines − Structure, Synthesis, and Functionalization

European Journal of Organic Chemistry, Volume 29, Issue 19, 22 May 2026.
1,2‐Diazetidines are saturated four‐membered heterocycles featuring two adjacent nitrogen atoms. Despite recent advances in their synthesis and promising potential in medicinal chemistry, the chemistry of these cyclic hydrazines remains underexplored.

Phase‐Transfer‐Catalyzed Interrupted Barton–Zard Reaction Between Electron‐Deficient Indoles and Benzophenone‐Derived Isocyanides

European Journal of Organic Chemistry, Volume 29, Issue 19, 22 May 2026.
A cascade reaction under phase‐transfer conditions between 3‐nitro indoles and isocyanomethylene dibenzenes affords the construction of pyrrolo[3,4‐b]indole cores. Control experiments provide insight into moderate product yields and clarify why the reaction is not amenable to asymmetric induction. A cascade reaction enabling the construction of pyrrolo[

Studies on Heterocyclic Compounds. XIV. 1, 3-Dipolar Cycloaddition Reaction of Dimethyl Acetylenedicarboxylate with Phenylhydrazones

Chemical and Pharmaceutical Bulletin, 1973
1, 3-Dipolar cycloaddition of aldehyde hydrazones with dimethyl acetylenedicarboxylate without solvent gives rise to dimethyl 1, 3-diphenylpyrazole-4, 5-dicarboxylate, and in some cases trimethyl 1-phenylpyrazole-3, 4, 5-tricarboxylate as a by-product.
