A convenient synthesis of 3-arylbenzo[b]thiophenes utilizing an interrupted Pummerer reaction of 2-(1-arylvinyl)phenyl ethyl sulfoxides is described. Thus, treatment of these sulfoxides, which were readily prepared from 2-sulfanylphenyl ketones or 2-fluoro-5-methoxybenzaldehyde, with acetic anhydride at 100 °C afforded 3-arylbenzo[b]thiophenes in reasonable yields.
描述了利用2-(1-芳基乙烯基)苯基乙基亚砜的间断Pummerer反应方便地合成3-芳基苯并[ b ]噻吩的方法。因此,在100℃下用乙酸酐处理由2-硫烷基苯基酮或2-氟-5-甲氧基苯甲醛容易制备的这些亚砜,以合理的收率得到了3-芳基苯并[ b ]噻吩。
