N-Benzylquinuclidinium bromide was ring opened by a series of heteronucleophiles, in the presence of cesium carbonate, to yield the corresponding N-benzyl-4-(2-hetero-ethyl)piperidines. The best yields were found with thiophenol (56%), phenol (55%), and benzimidazole (38%) as nucleophiles.
Ñ -Benzylquinuclidinium溴化物环通过一系列heteronucleophiles的打开,在碳酸铯的存在下,得到相应的Ñ苄基-4-(2-杂-乙基)哌啶。以苯硫酚(56%),苯酚(55%)和苯并咪唑(38%)为亲核试剂发现了最佳收率。
