thiosemicarbazide afforded the respective 4- and 5-acetoxy(5- and 4-methyl)thiosemicarbazones 33 and 40, which were then converted to their respective 4- and 5-hydroxy derivatives 34 and 41 by acid hydrolysis. The most active compounds synthesized were 4-aminoisoquinoline-1-carboxaldehyde thiosemicarbazone (9a) and 4-(methylamino)isoquinoline-1-carboxaldehyde thiosemicarbazone (9b), which both produced optimum
已经合成了各种取代的异喹啉-1-甲醛硫代半脲酮(12种化合物),并评估了患有L1210白血病的小鼠的抗肿瘤活性。4-溴-1-甲基异喹啉(4)与氢氧化铵,甲胺,乙胺和N-乙酰基乙二胺缩合得到相应的4-氨基,4-甲基氨基,4-乙基氨基和4-N-(乙酰乙基)氨基衍生物,然后将其转化为酰胺,然后氧化为醛,然后与硫代氨基甲酰肼缩合,生成硫代半氨基甲酮8a-c,9a-c和16。硝化4,然后用二氧化硒氧化,生成醛18,然后将其转化为醛18环状乙烯缩醛19。用吗啉将19缩合,然后催化还原硝基,并用硫代氨基脲处理,得到5-氨基-4-吗啉代异喹啉-1-羧甲醛硫代氨基脲(22)。N-氧化1,5-二甲基异喹啉,然后用乙酸酐重排,酸水解后得到1,5-二甲基-4-羟基异喹啉,将其转化为乙酸盐,然后氧化得到4-乙酰氧基-5-甲基异喹啉-1-甲醛(32)。磺化1,4-二甲基异喹啉,然后与氢氧化钾反应,乙酰化和氧化,得到5
