摘要
在碳酸钾存在下,对叔丁基硫桥杯[4]芳烃(1)分别与端基二溴代烷和碘甲烷反应,生成硫桥杯[4]芳烃衍生物2～4.含端基溴代的硫桥杯[4]芳烃衍生物2和4分别与2-巯基苯并噁唑在碳酸钾存在下反应,生成硫桥杯[4]芳烃衍生物5a～5d.通过1HNMR,13CNMR,IR,MS和元素分析等手段对产物进行了表征.同时,X射线分析确定了硫桥杯[4]芳烃5b的晶体结构.
p-tert-Butylthiacalix[4]arene （1） was firstly alkylated with methyl iodide or dibromoalkane with the aid of potassium carbonate to obtain thiacalix[4]arene 2～4,respectively.And the sequent reaction of thiacalix[4]arene intermediates 2 or 4 with 2-mercapto-benzoxazole in the presence of potassium carbonate afforded a series of p-tert-butylthiacalix[4]arenas 5a～5d bearing a benzoxazole group in good yields.All novel compounds were characterized by 1H NMR,13C NMR,IR,MS and elemental analysis.Meanwhile, the structure ofthiacalix[4]arene 5b was identified by X-ray diffraction analysis.
