Abstract 1,5‐Benzothiazepines and 1,5‐benzodiazepines have been synthesized in solvent‐free conditions from chalcones and o‐aminothiophenol or o‐phenylenediamine in the presence of inorganic support. Silica gel was found to be an effective support for the synthesis of 1,5‐benzothiazepines, whereas alumina was effective for the synthesis of 1,5‐benzodiazepines.
摘要 1,5-苯并二氮杂和 1,5-苯二氮卓类化合物在无溶剂条件下由查耳酮和邻氨基苯硫酚或邻苯二胺在无机载体存在下合成。发现硅胶是合成 1,5-苯并噻嗪类药物的有效载体,而氧化铝对合成 1,5-苯二氮卓类药物有效。
