Provided are β-substituted Morita-Baylis-Hillman (MBH) derivatives, pharmaceutically acceptable salts, hydrates, solvates and stereoisomers thereof. The derivatives may be prepared by preparing β-iodo-MBH esters from a variety of carbonyl compounds such as aldehydes and ketones, or imines in the presence of a Lewis acid as a basic backbone, and substituting iodide on a vinyl position with a variety of substituents. In addition, the β-substituted MBH derivatives have an excellent pharmaceutical effect in preventing and treating cancer.

Aluminum iodide has been found to promote the efficient and highly stereoselective synthesis of (Z)-β-iodo-α-(hydroxyalkyl)acrylates via one-pot three-component coupling reactions. This new system has made it possible to utilize various ketones as the electrophiles, in order to react with an aluminum allenoate intermediate for the synthesis of β-iodo Morita-Baylis-Hillman adducts with high yield and excellent Z-stereoselectivity (>99%).
