摘要: A simple and efficient synthesis of annulated 2,2′-bipyridinium salts with attached dihydrothiazole or dihydro-1,3-thiazine rings has been developed through tandem S-transalkylation/intramolecular ring closure 2,2′-bipyridine alkyl sulfides. The structures were confirmed by X-ray crystallographic analysis.
