  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吡喃糖苷中顺式-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。

  Novel benzoxaborole derivatives were designed as efficient catalysts for the highly site‐selective and protecting‐group‐free modification of polyols, such as carbohydrate. Additionally, the benzoxaborole catalyst could tolerate diverse modifications of polyols, including acylation, sulfonylation, alkylation, and glycosylation.

  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.

• Regioselective Benzoylation of Glycopyranosides by Benzoyl Chloride in the Presence of MoO₂(acac)₂
  作者：E. V. Evtushenko

  DOI：10.1080/07328303.2010.549258

  日期：2010.11.1

  Benzoylation of methyl and benzyl glycopyranosides by benzoyl chloride in the presence of MoO2(acac)(2) as a catalyst resulted in 3-benzoates with good yield and high regioselectivity. Simple synthesis of the monobenzoates of some glycopyranosides is suggested.
