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.
双功能手性硫脲已成功用作β-酮酯对映选择性氟化的有机催化剂。通过使用N-氟双苯磺酰亚胺(NFSI)作为氟化试剂,可以高收率获得对映体选择性良好至优异的相应产物。
