ChemInform Abstract: Hg/Pt‐Catalyzed Conversion of Bromo Alkynamines/Alkynols to Saturated and Unsaturated γ‐Butyrolactams/Lactones via Intramolecular Electrophilic Cyclization

Depending on the tether between the substrates′ bromoalkyne and the hydroxy or tosylamino group, respectively, the selective formation of saturated or unsaturated lactams, unsaturated lactones, oxazinones or α‐bromoketones is observed.
