Notes:
Intramolecular electrophilic cyclization reactions were performed with 1-(3-oxo-3-phenylpropyl)-1,2,5,6-tetrahydropyridine derivatives 1a-p in strong acids to give 4,6-diphenylsubstituted 1-azabicyclo[3.3.1]nonadienes 2a-p. Some qualitative observations were made on substituents and reaction conditions influencing the ring closure reaction. Naphthylsubstituted starting compounds 3a, b were converted into pentacyclic compounds 4a, b which represent a new ring system, suggesting the occurrence of a carbenium ion intermediate in the ring closure reaction. Some of the compounds 2a-p show remarkable antifungal and antibacterial effects.
