A simple and gram-scale synthesis of β-sulfonyl styrenes has been developed starting from one-pot PPA (polyphosphoric acid)-catalyzed 1,1-diacetoxylation of arylacetaldehydes (ArCH2CHO) with acetic anhydride (Ac2O) followed by deacetoxylative sulfonylation of the resulting 1,1-diacetate intermediate with sodium sulfinates (RSO2Na) in good yields under solvent-free conditions.
已开发出一种简单且克制的β-磺酰基苯乙烯合成方法,该方法从一锅式PPA(聚磷酸)催化的芳基乙醛(ArCH2CHO)与乙酸酐(Ac2O)的1,1-二乙酸酯化反应开始,随后在无溶剂条件下,通过将产生的1,1-二乙酸酯中间体与亚磺酸钠(RSO2Na)进行脱乙酰基磺酰化反应,以较高的产率合成β-磺酰基苯乙烯。
