We report a reliable and regiocontrolled alternative route to unsubstituted 2-aminothiopyrans and 2-aminothiophenes. These sulfur heterocycles were prepared by reaction of protected aminothiabutadiene 1 with acrylic dienophiles or acceptor-substituted halomethyl compounds. All compounds were fully characterized by IR, HRMS, and 13C and 1H NMR spectroscopy.
我们报告了制备未取代的 2-aminothiopyrans 和 2-aminothiophenes 的可靠且可控的替代途径。这些
硫杂环是通过受保护的
氨基
硫代
丁二烯 1 与
丙烯酸二烯烃或受体取代的卤代甲基化合物反应制备的。所有化合物都通过红外光谱、HRMS 以及 13C 和 1H NMR 光谱进行了全面表征。
