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-l-isochromanmethylamine. The new heterocycles so formed are useful for preparing derivatives having antiinflammatory, antibacterial or antifungal activities.
揭示了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。根据这种方法,例如带有乙醇基团的芳香核,如3,4-二甲氧基苯乙醇,与醛或酮或受保护的醛或酮,例如氨基乙醛二乙醚缩醛,在酸催化剂存在下缩合,生成多环杂环化合物,例如6,7-二甲氧基-1-异喹啉甲胺。因此形成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。
