A study directed toward the synthesis of saulatine (5,8,9,14a-tetrahydro-3,4,11,12-tetramethoxy-isoquino[1,2-b]benzazepine-6,14-dione) is described. The successful synthetic route consists of three steps starting with 3,4-dimethoxyphenethylamine and 2-bromo-(3,4-dimethoxy-2-ethoxycarbomethylphenyl)-acetate. It was found that the methoxy moieties present on the aromatic rings prohibit the use of the
描述了针对合成鼠尾草碱(5,8,9,14a-四氢-3,4,11,12-四甲氧基-异喹啉[1,2 - b ]苯并ze庚因-6,14-二酮)的研究。成功的合成路线包括三个步骤,从3,4-二甲氧基苯乙胺和2-溴-(3,4-二甲氧基-2-乙氧基羰基甲基苯基)-乙酸酯开始。发现存在于芳环上的甲氧基部分由于其在反应条件下的去甲基化趋势而阻止将分子内的弗瑞德-克来福特反应与路易斯酸催化剂一起用于环的构建。
