叠氮基-苯并[ b ]噻吩,-苯并噻唑,-苯并咪唑和-吲唑的合成和光解:新型的6,7-二氨基-苯并噻唑,-苯并咪唑和-吲唑和6-二乙基氨基-8 H-噻唑啉[5,4 - ç ]氮杂
摘要:
在过量仲胺存在下照射6-叠氮基苯并噻唑(4)-(9)(参见方案),得到相应的6,7-二氨基苯并噻唑(14)-(20),即6-氨基-8 H-噻唑并[5,4- c ]氮杂(21)-(24),两者的混合物或难处理的物质[如叠氮化物(9)的情况]。7-叠氮基-3-甲基苯并[照射b ]在过量的二乙胺的噻吩,得到7-氨基-3-甲基苯并[ b ]噻吩和3,3'-二甲基-7,7'- azobenzo痕量[ b]噻吩。6-叠氮基吲唑生成7-氨基-6-二乙基氨基吲唑(32)和5(6)-叠氮基苯并咪唑生成4(7)-氨基-5(6)-二乙基氨基苯并咪唑(33)和5(6)-氨基-4的混合物(7)-二乙氨基苯并咪唑(34)。将6-叠氮基苯并噻唑或其2-甲基衍生物在甲醇氧化物甲醇-二恶烷混合物中进行光解,分别得到相应的6-甲氧基-8 H-噻唑并[5,4- c ] a庚因,分别为(30)或(31)。
