摘要

抄録 Intramolecular cyclization reaction on the nitrogen atom of oximes of< I> p- hydroxybenzylacetone derivatives proceeds by the treatment with tetrabutylammonium perrhenate and trifluoromethanesulfonic acid in refluxing 1, 2-dichloroethane to afford azaspirodienones in good yield. The azaspirodienones are transformed into quinolines< I> via dienone-phenol rearrangement.
