Selective cleavage of an inert C-C bond followed by C-O/N bond formation through a long-distance aryl migrationfrom a carbon to a nitrogen center via Ag catalysis is reported. The migration products were easily converted into γ-hydroxy amines and tetrahydroquinoline derivatives in quantitative yields. Preliminary mechanistic studies indicated a radical pathway.
据报道,惰性 CC 键的选择性裂解,然后通过银催化从碳到氮中心的长距离芳基迁移形成 CO/N 键。迁移产物很容易转化为定量产率的 γ-羟基胺和四氢喹啉衍生物。初步的机理研究表明了一种激进的途径。

stereoselective synthesis and biological activity of NPS 1407 (4a), (S)-(-)-3-amino-1,1-bis(3-fluorophenyl)butane, a potent, stereoselective antagonist of the NMDA receptor, are described. The racemate (4) was found to be active at the NMDA receptor in an in vitro assay, prompting the synthesis of the individual stereoisomers. The S isomer (4a) was found to be 12 times more potent than the R isomer
