Abstract
In this thesis, we study on the ionic iodo carbocyclization of the α-iodocycloalkanones bearing a β-allenyl side chain. β-Allenyl substituted-α-iodocycloalkanones were prepared from 2-cyclohexenones by 1,4-addition and trapped as silyl enol ethers, then added in the mixture of NaI and m-CPBA afforded the α-iodocycloalkanones as starting materials. We use aluminum chloride and iodonium source to induce the ionic iodo carbocyclization. Because of the difficulty of separation, we did many experiments in order to prove that whether we got cyclized products or not. We supposed it may be the structure factor caused the reason why we didn’t get the cyclized products but only the addition products were observered.
