Abstract:
Benzoyl groups are commonly found in the structures of various pharmaceuticals, including non-steroidal anti-inflammatory drugs (NSAIDs), central nervous system stimulants, antihyperlipidemic agents, and hypnotics. Bicyclo[1.1.1]pentane-ketone group can serve as bioisostere for benzoyl groups, enhancing 3D spatial complexity, reducing off-target effects, and improving lipophilicity and solubility of the drug molecules. Herein, we present a visible light-induced approach for the synthesis of bicyclo[1.1.1]pentane-ketone, characterized by mild reaction temperature and excellent tolerance to oxidation-sensitive substituents such as -NH2, -methylthio and ferrocenyl group. The method delivers all products in moderate to high yields. Mechanistic studies revealed the formation of tButyl-bicyclo[1.1.1] pentane ether explained the requirement for stoichiometric amounts of tBuOOH rather than catalytic quantities, in despite of the redox-neutral nature of this reaction. © 2025 Fudan University
