Abstract

LaBt man 2-Lithiothiophen rnit N-Tosylaziridin oder N-Phenylsulfonylaziridin bei-20" C reagieren, so erfolgt der nucleophile Angriff an einem Aziridin-Kohlenstoffatom und fuhrt unter Ringoffnung zu den gewunschten Sulfonamiden 2a, b. Diese Sulfonamide konnen als Zwischenprodukte fur die Synthese von pharmakologisch interessanten Derivaten verwendet werden la).
