Palladium catalysed intramolecular coupling of aryl and benzylic halides and related tandem cyclisations. A simple synthesis of hippadine.
摘要:
A Pd(0)/R3Sn)2 (R = Me or n-Bu) catalyst system effects intramolecular aryl-aryl, benzyl-aryl, benzyl-benzyl coupling of aryl and benzyl halides in good yield. Polycyclisations can be achieved by relaying the coupling via an alkene or alkyne ''linker''. The methodology is exemplified by a short synthesis of hippadine.
