摘要: 以脱氢枞胺为原料,在三氟乙酸酐和乙酸酐保护其氨基后,经B环铬酸氧化转化成为(酮)N-三氟乙酰基-7-氧代脱氢枞胺(2a)和N-乙酰基-7-氧代脱氢枞胺(2b),酮再与盐酸氨基脲缩合形成(缩氨基脲)N-三氟乙酰基脱氢枞胺-7-氨基脲酰腙(3a)和N-乙酰基脱氢枞胺-7-氨基脲酰腙(3b),然后在氯化亚砜的处理下发生Hurd-Mori反应,环合生成(B环并1,2,3-噻二唑衍生物)N-三氟乙酰基脱氢枞胺-6-烯[7,6-d]-并-1,2,3-噻二唑(4a)和N-乙酰基脱氢枞胺-6-烯[7,6-d]-并-1,2,3-噻二唑(4b),最后在碱性条件下水解脱去氨基保护基,合成了脱氢枞胺-6-烯[7,6-d]-并-1,2,3-噻二唑(5)。通过FT-IR、1H NMR、13C NMR和ESI-MS等方法对2a3a4a4b5的结构进行了表征,进一步分析了4a4b5这3种新型脱氢枞胺1,2,3-噻二唑衍生物的谱图特征及结构差异。

Abstract: Dehydroabietylamine, the starting material, reacted with trifluoroacetic anhydride and acetic anhydride to protect amino group, then converted to ketones:N-trifluoroacetyldehydroabietylamine-7-one(2a) and N-acetyldehydroabietylamine-7-one(2b) by oxidation on ring-B with chromic, the obtained ketones were treated with semicarbazide hydrochloride to afford semicarbazones:N-trifluoroacetyldehydroabietylamine-7-one semicarbazone(3a) and N-acetyldehydroabietylamine-7-one semicarbazone (3b).Compounds 3a and 3b were transformed into ring-B fused 1, 2, 3-thiadiazole derivatives:N-trifluoroacetyldehydroabietylamine-6-ene[7, 6-d]-1, 2, 3-thiadiazole(4a) and N-acetyldehydroabietylamine-6-ene[7, 6-d]-1, 2, 3-thiadiazole(4b) by Hurd-Mori reaction with thionyl chloride.Finally, the amide were hydrolysised under alkaline condition to remove protecting groups, and gave dehydroabietylamine-6-ene[7, 6-d]-1, 2, 3-thiadiazole(5).The structures of three new synthesized dehydroabietylamine 1, 2, 3-thiadiazole derivatives 4a, 4b and 5 were characterized by FT-IR, 1H NMR, 13C NMR and ESI-MS.Their spectrum feature and structure difference were also analyzed.
