A Facile Synthesis of Novel Pyrazinobarrelenes from Bicyclo(2.2.2) octenediones.

-The synthesis of the title compounds (III), (V), and (VIII) by cyclocondensation of diones (I), (IV), and (VI), respectively, with diamines is described. Interestingly, reaction with the 1,3-diamine ( IX) only leads to the formation of the monocondensation product (X). -(NAIR, V.;
