Attack of MeMgl and PhMgBr in toluene on spiro[cyclohexane-1,3′-3H-indole] (1) in the presence of Cu2-Cl2 gives 2′-substituted spiro[cyclohexane-1,3′-indolines] in quantitative yields. Also, attack of PhCH2CH2MgBr on 1 in the presence of Cu2Cl2 afforded 2′-phenethyl, 2′-H and 2′-benzyl (or 2′-p-xylyl) derivatives in toluene (or p-xylene) as solvent.
在 Cu2-Cl2 存在下,甲苯中的 MeMgl 和 PhMgBr 对螺[环己烷-1,3'-3H-吲哚] (1) 的攻击以定量产率得到 2'-取代的螺[环己烷-1,3'-二氢吲哚] . 此外,在 Cu2Cl2 存在下 PhCH2CH2MgBr 对 1 的攻击在作为溶剂的甲苯(或对二甲苯)中提供 2'-苯乙基、2'-H 和 2'-苄基(或 2'-对二甲苯基)衍生物。
