Used as a key intermediate in organic synthesis, particularly in the preparation of complex natural products and pharmaceuticals. Its structure allows for selective functionalization at multiple sites, making it valuable in constructing sterically hindered or cyclic frameworks. Commonly employed in alkylation, iodination, and cross-coupling reactions due to the reactivity of both the enone system and the iodine substituent. Facilitates carbon–carbon bond formation through metal-catalyzed transformations, such as Stille or Suzuki couplings. Also utilized in the synthesis of steroids and terpenoids where dimethyl-substituted rings are present.
