Two expedient one-pot methods have been developed for synthesis of β-aryl-β-mercaptoketones using acetophenones, benzaldehydes and thiols as starting materials. The methods involve microwave irradiation (5 min) of 1:1 mixtures of acetophenones and benzaldehydes over neutral alumina supported anhydrous potassium carbonate or amberlyst-15 in the first step, and that is followed by addition of thiol to the resulting material and keeping at room temperature for 1.5 h.
我们开发了两种简便的一锅法合成β-芳基-β-巯基酮的工艺,使用苯乙酮、苯甲醛和硫醇作为起始原料。这两种方法包括以下步骤:首先,将苯乙酮和苯甲醛的1:1混合物在微波照射下(5分钟)与中性氧化铝负载的无水碳酸钾或安伯利斯特-15反应;然后,向所得产物中加入硫醇,并在室温下保持1.5小时。
