(1—3) were prepared by a modified Koenigs‐Knorr synthesis. As the alkaline hydrolysis of perpivaloylated methyl (2,3‐dichlorophenyl)‐ glucuronate 1a led to a dehydrated glucuronide, the preparation of peracetylated methyl dichlorophenylglucuronates with subsequent cleavage of the ester bindings under mild conditions was preferred.
2,3-、3,4- 和 2,6-二氯苯酚 (1-3) 的 β-D-葡萄糖醛酸苷通过改良的 Koenigs-Knorr 合成法制备。由于全新戊酰化甲基 (2,3-二氯苯基)-葡萄糖醛酸 1a 的碱性水解导致脱水葡萄糖醛酸,因此优选制备过乙酰化二氯苯基葡萄糖醛酸甲酯,随后在温和条件下裂解酯键。
