Abstract
The intramolecular reductive coupling reactions of ketomalononitriles induced by a low-valent titanium reagent were studied. Benzo[4,5]indene, acridine and quinoline derivatives are prepared in good yields under neutral and mild conditions.
Key words
low-valent titanium - benzo[4,5]indene - acridine - quinoline
