carbohydrazide 1 with phthalic anhydride afforded 12,13-diphenyl-6H-pyridazino-[3″,4″: 5′,4′]thieno[3′,2′:4,5]pyrimido-[2,1-a]phthalazine-5,6-dione, (6) which underwent further transformation to the related compounds.
以5-氨基-3,4-二苯基噻吩并[2,3-c]哒嗪为原料合成了7-取代的3,4-二苯基嘧啶并[4',5':4,5]噻吩并[2,3-c]哒嗪- 6-碳酰肼 (1)。碳酰肼1与邻苯二甲酸酐反应得到12,13-二苯基-6H-哒嗪基-[3″,4″: 5',4']噻吩并[3',2':4,5]嘧啶-[2,1- a] phthalazine-5,6-dione, (6) 进一步转化为相关化合物。
