  • Catalytic Activation of <i>Cis</i>-Vicinal Diols by Boronic Acids: Site-Selective Acylation of Carbohydrates
    作者:Naoyuki Shimada、Yuki Nakamura、Takayuki Ochiai、Kazuishi Makino
    DOI:10.1021/acs.orglett.9b01231
    日期:2019.5.17
    imidazole-containing organoboronic acid catalysts is described. This catalytic process with low catalyst loading enables the introduction of a wide variety of acyl functional groups into the equatorial position of cis-vicinal diols in unprotected hexapyranosides with excellent site selectivity. This is the first example that uses a Lewis base-containing boronic acid to enhance the nucleophilicity of
    描述了通过使用稳定的,可储存的且易于处理的含咪唑的有机硼酸催化剂对未保护的碳水化合物进行位点选择性酰化。这种具有低催化剂负载量的催化方法能够将多种酰基官能团引入到未保护的六喃糖苷中顺式-邻位二醇的赤道位置,具有出色的位点选择性。这是使用含路易斯碱的硼酸来增强羟基的亲核性的第一个例子。
  • Borinic Acid-Catalyzed Regioselective Acylation of Carbohydrate Derivatives
    作者:Doris Lee、Mark S. Taylor
    DOI:10.1021/ja110332r
    日期:2011.3.23
    Reversible covalent interactions of organoboron compounds are exploited as the basis for regioselective borinic acid-catalyzed acylations of polyols. This catalytic protocol enables differentiation of the secondary OH groups of a wide range of carbohydrate derivatives with diverse acid chloride and chloroformate reagents, using a structurally simple diarylborinic acid-derived catalyst.
    有机化合物的可逆共价相互作用被用作区域选择性硼酸催化多元醇酰化的基础。该催化协议使用结构简单的二芳基硼酸衍生催化剂,能够区分具有不同酰氯甲酸酯试剂的各种碳水化合物生物的二级 OH 基团。
  • Regioselective Sulfonylation/Acylation of Carbohydrates Catalyzed by FeCl<sub>3</sub> Combined with Benzoyltrifluoroacetone and Its Mechanism Study
    作者:Jian Lv、Jia-Jia Zhu、Yu Liu、Hai Dong
    DOI:10.1021/acs.joc.9b03128
    日期:2020.3.6
    A catalytic amount of FeCl3 combined with benzoyl trifluoroacetone (Hbtfa) (FeCl3/Hbtfa = 1/2) was used to catalyze sulfonylation/acylation of diols and polyols using diisopropylethylamine (DIPEA) or potassium carbonate (K2CO3) as a base. The catalytic system exhibited high catalytic activity, leading to excellent isolated yields of sulfonylation/acylation products with high regioselectivities. Mechanism
    使用二异丙基乙胺(DIPEA)或碳酸(K2CO3)作为碱,将催化量的FeCl3与苯甲酰基三丙酮(Hbtfa)(FeCl3 / Hbtfa = 1/2)结合用于催化二醇和多元醇的磺酰化/酰化。该催化体系表现出高催化活性,导致具有高区域选择性的磺酰化/酰化产物的优异分离产率。机理研究表明,FeCl3最初在碱性条件下于室温下于溶剂乙腈中以两倍的Hbtfa量形成[Fe(btfa)3](btfa =苯甲酰基三丙酮酸酯)。然后,在碱的存在下,Fe(btfa)3和底物的两个羟基形成五元或六元环中间体。环状中间体和磺酰化试剂之间的随后反应导致底物的选择性磺酰化。所有关键中间体均在高分辨率质谱分析中捕获,因此首次证明了这种机理。
  • An inexpensive catalyst, Fe(acac)<sub>3</sub>, for regio/site-selective acylation of diols and carbohydrates containing a 1,2-<i>cis</i>-diol
    作者:Jian Lv、Jian-Tao Ge、Tao Luo、Hai Dong
    DOI:10.1039/c8gc00428e
    日期:——
    This work describes the [Fe(acac)3] (acac = acetylacetonate)-catalyzed, regio/site-selective acylation of 1,2- and 1,3-diols and glycosides containing a cis-vicinal diol. The iron(III) catalysts initially formed cyclic dioxolane-type intermediates with substrates between the iron(III) species and vicinal diols, and the efficient and selective acylation of one hydroxyl group was subsequently achieved
    这项工作描述了[Fe(acac)3 ](acac =乙酰丙酮酸酯)催化的1,2-和1,3-二醇和含有顺式邻位二醇的糖苷的区域/位点选择性酰化。(III)催化剂最初形成环状二氧戊环型中间体,底物在(III)物种与邻位二醇之间,随后通过在二异丙基乙胺(DIPEA)存在下添加酰化试剂,实现一个羟基的有效和选择性酰化)在温和的条件下。该反应通常产生高选择性和高分离产率,并具有与二丁基氧化介导的方案相同的保护模式。
  • DBN-Catalyzed Regioselective Acylation of Carbohydrates and Diols in Ethyl Acetate
    作者:Bo Ren、Mengyao Zhang、Shijie Xu、Lu Gan、Li Zhang、Lin Tang
    DOI:10.1002/ejoc.201900776
    日期:2019.8.7
    The 1,5‐diazabicyclo[4.3.0]non‐5‐ene (DBN)‐catalyzed, highly efficient and relatively green regioselective acylation of carbohydrates and diols is firstly developed. The hydroxyl groups can be selectively acylated by the corresponding anhydride in EtOAc in the presence of a catalytic amount (as low as 0.1 equiv.) of DBN at room temperature to 40 °C.
    碳水化合物和二醇的1,5-二氮杂双环[4.3.0] non-5-ene(DBN)催化,高效且相对绿色的区域选择性酰化反应是最先开发的。在室温至40°C下,在存在催化量(低至0.1当量)的DBN的情况下,可用相应的酸酐在EtOAc中将羟基选择性地酰化。
