Stellane at the Forefront: Derivatization and Reactivity Studies of a Promising Saturated Bioisostere of ortho-Substituted Benzenes

This work highlights stellane's cage stability and derivatization opportunities. A diverse range of building blocks were synthesized using modern synthesis protocols to demonstrate stellane's reactivity and chemical tolerance across different reaction systems, proving its promise as a bioisosteric scaffold. It can be utilized in scaffold-based molecular design and is superior in terms of topological precision compared to existing
