Abstract

Aziridinyllithiums were generated from sulfinylaziridines by a sulfoxide–lithium exchange reaction of sulfoxides with tert-butyllithium at low temperature. The generated aziridinyllithiums were found to be stable in THF at below− 30° C and they are reactive with several electrophiles such as carbonyl compounds, ethyl chloroformate, and phenyl isocyanate. The reactivities of the aziridinyllithiums having several alkyl groups were ...
