Resumen de Synthesis ofSome Novel Thieno[2,3-c] pyridazines, pyrimidothienopyridazines and related Triarolo [ 1 "5": 1 ',6' ] pyrimido [ 4 ',5': 4,5 ] thieno [2,3-c] pyridazines

• Se sintetizan 3,4-dimetiltieno [2,3-c]piridazinas 5,6-disubs- tituidas (5a-d, 6 y 7). El 5-amino-3,4-dimetiltieno[2,3- c] piridazina-6-carbonitrilo (5b) se usa como intermedio clave en la síntesis de nuevos derivados de pirimi- do [4' ,5':4,5]tieno[2,3-c]piridazina (8-12) y 1,2,4-triazo- 10 [1 ",5":1' ,6'] pirimido [4' ,5':4,5]tieno [2,3-c] piridazina (14, 15).
