✦ Synopsis

Y-Shaped ambident dianions 1-6 were reacted with cyclization reactions generally proceeded with good regioselectivity which is controlled by the heteroatoms of the dielectrophilic oxalic acid-bis(imidoyl)dichlorides 7 providing a convenient access to novel N-heterocycles 8-13 dianion reagents. containing a heteroanalogous oxalic acid unit.
