摘要

Attack of MeMgl and PhMgBr in toluene on spiro [cyclohexane-1, 3′-3H-indole](1) in the presence of Cu 2-Cl 2 gives 2′-substituted spiro [cyclohexane-1, 3′-indolines] in quantitative yields. Also, attack of PhCH 2 CH 2 MgBr on 1 in the presence of Cu 2 Cl 2 afforded 2′-phenethyl, 2′-H and 2′-benzyl (or 2′-p-xylyl) derivatives in toluene (or p- xylene) as solvent.
