The condensation of pyridine-2, 4,6-tricarboxtrisamidrazone 1 with 1,2-dicarbonyl compounds 2 - 3 leads to trisubstituted 1,2,4-triazines 4 - 6. These 1,2,4-triazines can be easily transformed to superbranched pyridines 7 - 9 by [4+2] cycloaddition with norborna-2,5-diene followed by [4+2] cycloreversions of nitrogen and cyclopentadiene. This reaction sequence offers a new, simple and general access to superbranched oligopyridines. (C) 1998 Elsevier Science Ltd. All rights reserved.
