Construction of Tetrahydropyridobenzimidazoles via Ni–Al Bimetal-Catalyzed Tandem C(sp2)/C(sp3)–H Annulation

Abstract Tetrahydropyridobenzimidazoles are privileged heterocyclic motifs prevalent in bioactive molecules. While transition-metal-catalyzed C–H annulation of benzimidazoles has emerged as a highly atom-economical approach, current strategies are largely limited to single C–H an...

Hybrid 5D Gravity (H5DG): A Step Towards Unification

This record contains the complete sixteen-paper corpus of Hybrid 5D Gravity (H5DG), assembled as a single ordered reference edition. H5DG investigates how far a single-boundary five-dimensional braneworld can provide a unified framework for gravitational phenomenology, from the S...

Hybrid 5D Gravity (H5DG): A Step Towards Unification

Hybrid 5D Gravity (H5DG) is a fourteen-paper theory of gravity and gravitational unification that investigates whether a deliberately constrained five-dimensional braneworld can connect relativistic gravity, galactic dynamics, gravitational lensing, a collisionless dark sector, p...
