TMP-锌酸钠[(TMEDA)Na(TMP)((t)Bu)Zn((t)Bu)]可以在环境温度下在己烷溶液中使N-Boc吡咯烷脱锌,而在甲苯中,杂环的捕获的α-碳负离子攻击溶剂,引发级联反应,最终产生吡咯烷取代的烯醇化物。
Sodium TMP-zincate, [(TMEDA)Na(TMP)((t)Bu)Zn((t)Bu)], can deproto-zincate N-Boc pyrrolidine at ambient temperature in hexane solution, whereas in toluene the captured α-carbanion of the heterocycle attacks the solvent setting off a cascade of reactions that ultimately produce a pyrrolidine-substituted enolate.
