  • H-Bonding Activation in Highly Regioselective Acetylation of Diols
    作者:Yixuan Zhou、Martin Rahm、Bin Wu、Xiaoling Zhang、Bo Ren、Hai Dong

    acetylation of vicinal and 1,3-diols is presented. Herein, the acetylation of the hydroxyl group with acetic anhydride can be activated by the formation of H-bonds between the hydroxyl group and anions. The reaction exhibits high regioselectivity when a catalytic amount of tetrabutylammonium acetate is employed. Mechanistic studies indicated that acetate anion forms dual H-bonding complexes with the diol
    介绍了邻位和1,3-二醇的区域选择性乙酰化中的H键活化。在此,可以通过在羟基与阴离子之间形成H键来使羟基被乙酸酐乙酰化。当使用催化量的乙酸四丁基时,该反应表现出高的区域选择性。机理研究表明,乙酸根阴离子与二醇形成双H键复合物,这有助于随后的区域选择性单乙酰化。
  • Temperature-Controlled Regioselectivity in the Reductive Cleavage of <i>p</i>-Methoxybenzylidene Acetals

    functional groups, including allyl and enol ethers. The presence of water does not interfere with reductive ring opening and may contribute toward in situ generation of H+ as a catalyst for 6-O-PMB ether formation. Reductive cleavage under rigorously aprotic conditions is greatly decelerated, and yields only the 4-O-PMB ether. The temperature-dependent reductive cleavage of the 4,6-acetal can be described in
    可以通过调节反应温度和试剂浓度来调节吡咯型4,6-对-甲氧基亚苄基乙缩醛与BH 3 / Bu 2 BOTf在THF中的区域选择性开环。在0还原裂解℃下导致的专属形成4- ø - p甲氧基苄基(PMB)醚,而反应在-78℃下产生的6- ö -PMB醚以高收率。观察到后一种条件与包括烯丙基醚和烯醇醚在内的各种酸敏感性官能团相容。的存在不会干扰还原性开环,并且可能有助于原位生成H +作为6- O的催化剂-PMB醚的形成。在严格非质子条件下的还原裂解被大大减速,并且仅产生4- O- PMB醚。4,6-乙缩醛的温度依赖性还原裂解可通过动力学与热力学控制来描述:在较高温度下,更易接近的O-6的路易斯酸配位是有利的,而更碱性但空间受限的质子化O-4在低温下占主导地位。

  • The Function of the 5-Hydroxymethyl Group of Lactose in Enzymatic Hydrolysis with beta-Galactosidase from E. coli.

    A series of 6-substituted methyl lactoside derivatives together with methyl allolactoside and (6S)-methyl [6-H-2]lactoside have been synthesized and characterized by NMR spectroscopy. All compounds were tested as substrates for the enzyme beta-galactosidase from E. coli using progress curve kinetic methology both in single-substrate and competition experiments. The results show that the hydrolysis of methyl lactoside to a large extent takes place through an intramolecular trans-glycosidation reaction via allolactoside. Furthermore, methyl 6-amino-6-deoxy-D-glucopyranoside proved to be an inhibitor for the enzymatic hydrolysis.
