Abstract

3‐Chloro‐2‐pyrrolidinocyclohexene (3) in the presence of silver tetrafluoroborate in methylene chloride at −60° underwent cycloadditions with various 1,3‐dienes; the resulting iminium tetrafluoroborate salts 4a–8a were hydrolysed to give the bicyclic and tricyclic ketones 4b–8b. The addition reactions can be regarded as [3+4]‐cycloadditions of an intermediate 2‐aminoallyl cation.
