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.
A geometric-selective synthesis of (E)-beta-iodo Morita-Baylis-Hiliman esters has been developed through a three-component aldol-type reaction using BF3 center dot Et2O and TMS-1. The synthetic utility of the (E)-beta-iodo Morita-Baylis-Hillman esters was demonstrated in the first reported short synthesis of secokotomolide A.
