In an extension of recently reported syntheses of the I-azaphenoxathiin nucleus as well as several 7-substituted analogs, the synthesis of several 9-substituted members of this series is now reported. In addition, the first 13C-nmr spectral evidence of an interaction between a sulfur atom and the oxygen of an ortho-nilro group which has been previously observed only in X-ray erystallographic studies
在最近报道的I-氮杂吩沙星蛋白核以及几种7-取代的类似物的合成的扩展中,现在报道了该系列的几种9-取代的成员的合成。另外,还描述了硫原子与邻-硝基基团的氧之间相互作用的最初的13 C-nmr光谱证据,这以前仅在X射线眼图学研究中才观察到。还介绍了这种相互作用对导致9-取代的J-氮杂苯并噻吩啶核环化的反应路径的可能后果。
