摘要: 糖酯类化合物具有广泛的生理活性,如抗菌、抗肿瘤等。1987年Trivedi等首次使用苯甲酰基保护的溴化α-D-葡萄糖与桂皮酸类在相转移催化剂三甲基十六烷基溴化铵的存在下反应,合成了收率为53%~82%的糖酯,此结果与Inch的结果不一致。

Abstract: 2,3,4,6-Tetra-O-acetyl-α-D-glucosyl bromide reacts with carboxylic acids in the presence of phase transfer catalysts to give carbohydrate esters. There are many advantages in this method, such as good yields, mild reaction conditions and high stereospecificity. The results conclusively disproved a report by Inch and his co-workers that the phase-transfer method requires a nonparticipating group at C-2 or C-6 in the carbohydrate moiety.

Key words: Phase-transfer catalysis, Carbohydrate ester, Tetrabutylammonium bromide
