  • First application of hexaaquaaluminium(III) tetrafluoroborate as a mild, recyclable, non-hygroscopic acid catalyst in organic synthesis: a simple and efficient protocol for the multigram scale synthesis of 3,4-dihydropyrimidinones by Biginelli reaction

    used as a mild acid catalyst in organic synthesis. A simple method of its preparation based on the reaction of aluminium triisopropoxide and tetrafluoroboric acid in isopropanol afforded catalyst of high purity and activity. The three-component Biginelli condensation of acetoacetate esters, urea and aldehydes catalyzed by 10 mol % of [Al(H2O)6](BF4)3 in refluxing acetonitrile afforded 3,4-dihydropyrimidonones
    首次将四硼酸六铝铝(III)用作有机合成中的弱酸催化剂。基于三异丙醇铝和四硼酸异丙醇中反应的简单制备方法提供了高纯度和活性的催化剂。10 mol%的[Al(H 2 O)6 ](BF 4)3催化的乙酰乙酸酯,和醛的三组分Biginelli缩合反应在回流的乙腈中,以克数为单位,以高至高收率得到3,4-二氢嘧啶酮。对酸敏感性反应物(例如噻吩基和呋喃甲醛)的耐受性,对位阻β-酮酸酯的适用性以及在不损失催化活性的情况下简单的可回收性,使得该催化剂成为文献方法的良好替代品。该反应的机理包括形成所谓的“基-巴豆酸酯”而不是布朗斯台德型催化剂中发现的相应的酰基亚胺基中间体。
