Molina, Pedro,Alajarin, Mateo,Vidal, Angel
, p. 7 - 8 (1990)
A short synthesis of 1,9-diazaphenalene derivatives (8) based on a new method of two consecutive pyridine annelations which involves cyclization of conjugated carbodiimides (5) is described.
One-pot Preparation of Derivatives of the Unknown Fluorenoisoquinoline Ring from Conjugated Ketenimines by a Consecutive Electrocyclic Ring-closure/Claisen Rearrangement/Intramolecular Diels-Alder Cycloaddition/Double Aromatization Process
Molina, Pedro,Alajarin, Mateo,Vidal, Angel,Feneau-Dupont, J.,Declercq, J. P.
, p. 829 - 831 (2007/10/02)
A short synthesis of fluorenoisoquinoline derivatives (8) based on a new method of three consecutive annelations which involves thermal cyclization of conjugated ketenimines is described; the crystal structure of (8) has been determined.
