Selectfluor as “Fluorine-Free” Functional Reagent Applied to Organic Synthesis under Transition Metal-Free Conditions Kong Yaolei, Sun Xiaotong, Weng Jianquan. Recent Progress on Quinone Imine Ketals: Synthesis and Applications Key words: 2-cycloenone, synthesis, dialkylphenylsilyl cuprate, 1,4-addition, 2-substituted-3-silylcycloalkanone, stereoselectivity All products were characterized by IR, 1H NMR, 13C NMR, MS and HRMS spectra. It was also observed that arylmethyl bromides reacted with enolates resulting from 1,4-addition of dimethylphenylsilyl cuprate to 2-cycloenones giving exclusively trans isomers. However, it was first found that the addition gave very high trans selectivity independent of the aryl group, ring size and substituents on the silicon atom by quenching the reactions with methanol at room temperature. It was found that the stereoselectivity of the 1,4-addition of dialkylphenylsilyl cuprates to 2-aryl-2-cycloenones depended on the nature of aryl group and ring size by quenching the reactions with saturated NH 4Cl solution at 0 ℃.

The stereoselectivity of 1,4-addition of dialkylphenylsilyl cuprates to 2-cycloenones was investigated and meantime a series of new 2-substituted-3-silylcycloalkanones were synthesized.
