, p. 2599 - 2602 (1996)
A one-pot procedure for the direct and surprisingly simple formation of the title compounds by the reactions of pyridinium dicyanomethylides with benzyne are described together with full details of the 1H and 13C NMR data for the products.

, p. 869 - 870 (2007/10/02)
Benzoisoindoloindolizines, a novel kind of 18? heterocycles, have been prepared by one pot succesive 1,3-dipolar cycloadditions of pyridinium dicyanomethylides with benzyne.
