A process applicable to the preparation of a wide variety of novel polycyclic heterocycles having a newly-formed pyran ring is disclosed. According to the process an aromatic nucleus bearing an ethanol group, for example, 3,4-dimethoxyphenethyl alcohol, is condensed with an aldehyde or ketone or a protected aldehyde or ketone, for example, aminoactaldehyde diethyl acetal, in the presence of an acid catalyst to afford the polycyclic heterocycle, for example, 6,7-dimethoxy-1-isochromanmethylamine. The new heterocycles so formed are useful for preparing derivatives having antiinflammatory, antibacterial or antifungal activities.
本发明涉及一种适用于制备多种新型多环杂环化合物的方法,其中含有新形成的吡喃环。根据该方法,例如3,4-二甲氧基苯乙醇等含有乙醇基的芳香核与醛或酮或保护醛或酮(例如氨基乙醛双乙醇缩醛)在酸催化剂的存在下缩合,以得到多环杂环化合物,例如6,7-二甲氧基-1-异色苯并甲胺。所得到的新杂环化合物可用于制备具有抗炎、抗菌或抗真菌活性的衍生物。
