| Abstract: | The reaction of unsaturated aminoketones with dimeric malononitrile gives the amides IV, V and VI beside the already described 2-(dicyano-methylen)-3-cyano-1,2-dihydro-pyridines. Acidic hydrolysis leads to the 1,5,6,7-tetrahydro-pyrido4,3-b]-pyridine-5,7-diones VII and VIII. *** DIRECT SUPPORT *** A3615112 00030 |
