The development of an opticallypure monofluoromethylthiolating reagent based on Oppolzer's camphorsultam auxiliary (1S)-(−)-N-monofluoromethylthio-7,7-dichloro-2,10-camphorsultam 1b was described. Reagents 1b reacted with two types of substrates including oxazolone and oxindole derivatives with good to excellent enantioselectivities under mild conditions, thus representing the first available method
描述了基于 Oppolzer 的樟脑磺胺辅助剂 (1S)-(-)- N -monofluoromethylthio-7,7-dichloro-2,10-camphorsultam 1b的光学纯单氟甲硫基化试剂的开发。试剂1b与两种类型的底物反应,包括恶唑酮和羟吲哚衍生物,在温和条件下具有良好到优异的对映选择性,因此代表了我们获得单氟甲基硫醇化立体中心的第一种可用方法。
