SYNRHESIS OF NEW CONDENSED ANALOGS OF ISOINDOLINIUM SALTS
Chukhadzhyan, E. O.,Chukhadzhyan, El. O.,Shakhatuni, K. G.,Babayan, A. T.
, p. 594 - 596 (1991)
Quaternary ammonium salts that contain a 3-(α-naphthyl)propargyl group in addition to a group of the propargyl type undergo intramolecular cyclization of the diene-synthesis type under base-catalysis conditions to give condensed isoindolinium analogs.
