1,2‐Diazetidines − Structure, Synthesis, and Functionalization
European Journal of Organic Chemistry, EarlyView.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.

European Journal of Organic Chemistry, EarlyView.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[
