We have previously attempted to prepare 5-(4-morpholinyl)-2-aminothiophene (3) by reducing 5-(4-morpholinyl)-2-nitrothiophene (2), to prepare a precursor for the preparation of thienyloxazolidinones as potential linezolid-like antibiotics. This strategy failed, but allowed us to define an interesting reductive aromatization reaction. We have now succeeded in producing thienyloxazolidinones using an
我们之前已经尝试了制备5-(4-吗啉基)-2-氨基噻吩(3通过减少5-(4-吗啉基)-2-硝基噻吩()2),以制备前体用于制备thienyloxazolidinones的作为潜在linezolid-像抗生素。该策略失败了,但使我们能够定义一个有趣的还原性芳构化反应。现在,我们已经使用另一种策略成功地生产了噻吩并恶唑烷酮,它是由5-(4-吗啉基)噻吩-2-甲醛(8)引发的。该信函描述了噻吩恶唑烷酮14的合成,噻吩恶唑烷酮14是制备具有噻吩核心的新型恶唑烷酮抗生素的关键中间体。
