  Regio- and Stereoselective Addition of Allylmetal Reagents to Pyridinium−π and Quinolinium−π Complexes

  摘要：

  Regio- and stereoselective allylation of pyridinium and quinolinium salts was performed by the addition of allylindium and allyltributyltin reagents toward intermediary cation-pi complexes. The reaction with allylindium and allyltributyltin reagents afforded a 1,2-adduct, whereas the addition of a prenylindium reagent gave a 1,4-adduct with good regio- and stereoselectivities. X-ray structural analysis, H-1 NMR studies, and DFT calculations elucidated the intermediary cation-pi complex formation with face-to-face orientation.
