Synthesis of the ester side chains of homoharringtonine and harringtonine using lactones as building blocks

The efficient synthesis of the ester side chains of homoharringtonine and harringtonine using lactones as building blocks has been developed. The synthesis used classic reactions from readily available starting materials. Reactions of the lactone bearing
