Used as a key intermediate in organic synthesis, particularly in the formation of cyclohexene derivatives through nucleophilic substitution and cross-coupling reactions. Its trifluoromethylsulfonyloxy group acts as a good leaving group, making it highly reactive in palladium-catalyzed reactions such as Suzuki and Heck couplings. It is also employed in the preparation of functionalized carbocycles for pharmaceuticals and agrochemicals, where the ethyl ester moiety can be further modified or hydrolyzed. Its reactivity and structural features make it valuable in building complex molecules in medicinal chemistry research.
