  • Thiourea-Catalyzed Enantioselective Fluorination of β-Keto Esters
    作者:Junxing Xu、Yulai Hu、Danfeng Huang、Ke-Hu Wang、Changming Xu、Teng Niu
    DOI:10.1002/adsc.201100660
    日期:2012.2
    Bifunctional chiral thioureas have been successfully used as organocatalysts in enantioselective fluorinations of β-keto esters. The corresponding products could be obtained with good to excellent enantioselectivity in high yields by using N-fluorobisbenzenesulphonimide (NFSI) as fluorination reagent.

    A new kind of mono-oxazoline ligands which combined diaryl methyl units and chiral oxazoline units together using pyridine as linker was prepared. Their applications in enantioselective electrophilic fluorination of beta-ketoesters by NFSI were investigated, and the corresponding products were obtained in excellent yield (up to 90%) and good enantioselectivity (78%) in CH2Cl2 at -60 degrees C.
