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[

A New Synthetic Approach to the Preparation of Indolo[3,2‐c]quinolines From Sulfonylalkyl Indoles

Advanced Synthesis &Catalysis, Volume 368, Issue 10, 19 May 2026.
Functionalized indolo[3,2‐c]quinolines can be efficiently prepared from sulfonylalkyl indoles by a cascade process involving reduction, vinylogous aza‐Michael and aromatization reactions triggered by zinc powder in acetic acid at reflux. The reductive cyclization of sulfonylalkyl indoles obtained from 2‐(o‐nitroaryl)indoles, provides an efficient ...
