Recent Approaches for the Synthesis of Pyridine and Quinoline Cores Present in Natural Products

Advanced Synthesis &Catalysis, Volume 368, Issue 10, 19 May 2026.
An anthology of the most recent methods used to synthesize pyridines and quinolines found in natural products over the last decade. Pyridines, quinolines, and their derivatives represent a class of significant heterocyclic compounds that are prevalent in a multitude of natural products, including alkaloids found in plants, fungi, insects, marine ...

Zn(OTf)2‐Catalyzed Dehydrocoupling of Terminal Alkynes with Diisopropylaminoborane: A Modular Route to Mono‐ and Dialkynylboranes

Advanced Synthesis &Catalysis, Volume 368, Issue 10, 19 May 2026.
We report a Zn(OTf)2‐catalyzed dehydrocoupling of terminal alkynes with diisopropylaminoborane (DIPOB), which enables the selective synthesis of mono‐ and dialkynylboranes under mild conditions. This method provides a versatile platform for accessing stable tetracoordinate alkynylborons while effectively suppressing hydroboration side reactions.

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 ...

Isolation und Reaktivtät eines quadratisch‐planaren Trisamidosilans

Angewandte Chemie, Volume 138, Issue 21, 18 May 2026.
Wir berichten über die Synthese und umfassende Charakterisierung eines quadratisch‐planaren Si(+IV)‐Hydrids, das von einem unsymmetrischen, trianionischen und dearomatisierten N,N,N‐Pincerliganden stabilisiert wird. Dieses System ermöglicht eine Element–Liganden‐kooperative Reaktivität als Alternative zur siliciumzentrierten Redoxchemie und erweitert ...

Isolation and Reactivity of a Square‐Planar Trisamido Silane

Angewandte Chemie International Edition, Volume 65, Issue 21, 18 May 2026.
We report the synthesis and comprehensive characterisation of a square‐planar Si(+IV) hydride supported by an unsymmetric, trianionic and dearomatised N,N,N‐pincer ligand. This system enables element–ligand cooperative reactivity as an alternative to silicon‐centred redox chemistry, illuminating a largely unexplored regime in high‐valent silicon ...
