  Regioselective Benzoylation of Glycopyranosides by Benzoyl Chloride in the Presence of MoO₂(acac)₂

  摘要：

  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.

  Benzoylation of methyl and benzyl glycopyranosides by benzoic anhydride in acetonitrile in the presence of copper(II) trifluoroacetate as a promoter has given monobenzoates with a good yield and high regioselectivity. The composition of monobenzoates depended both on a configuration of hydroxyl groups and on a configuration of aglycone. The simple syntheses of the monobenzoates of some glycosides are

  在三氟乙酸铜（II）作为促进剂的存在下，在乙腈中通过苯甲酸酐在苯甲腈中对甲基和苄基吡喃葡萄糖苷进行苯甲酰化，得到了单苯甲酸酯，具有良好的收率和较高的区域选择性。单苯甲酸酯的组成取决于羟基的构型和糖苷配基的构型。提供了一些糖苷的单苯甲酸酯的简单合成。
