1,3-Dioxoisoindolin-2-yl cyclohexanecarboxylate is a specialty chemical intermediate, specifically an N-acyloxyphthalimide ester derived from N-hydroxyphthalimide and cyclohexanecarboxylic acid. It functions as a bench-stable acyl donor in transition-metal-catalyzed decarboxylative cross-coupling reactions, enabling efficient C-C and C-N bond formations for the synthesis of ketones, amides, and other acyl derivatives. This compound is widely used in pharmaceutical chemistry for constructing complex drug candidates, including those targeting kinases and other therapeutic areas. It also serves as a building block in heterocyclic synthesis, agrochemical development for novel pesticides, and materials science for functional organic materials with enhanced stability.
