Different strategies for the synthesis of 2′-hydroxy-4′-methylsulfonylacetophenone are reported in the present paper. This compound is considered as a key synthon for the synthesis of new flavonoid derivatives designed as potential cyclooxygenase-2 inhibitors. The retrosynthetic approach via 3′-methylsulfonylacetophenone, which included three synthetic pathways, did not allow us to obtain the expected
摘要 本文报道了合成 2'-羟基-4'-甲基磺酰苯乙酮的不同策略。该化合物被认为是合成新的类黄酮衍生物的关键合成子,这些衍生物被设计为潜在的环氧合酶 2 抑制剂。通过 3'-甲基磺酰苯乙酮的逆合成方法,包括三个合成途径,不允许我们获得预期的化合物。然而,3-巯基苯酚的合成分三步得到所需的苯乙酮:苯硫酚甲基化、Friedel-Crafts 乙酰化和硫化物氧化成相应的砜。所需的化合物 2'-羟基-4'-甲基磺酰基苯乙酮将用作合成子,用于制备新的类黄酮衍生物,如 2'-羟基查耳酮、黄烷酮、黄酮和黄酮醇。
