Partial benzylation of methyl α-D-galactopyranoside with benzyl chloride and LiOH selectively gave the 2,3,6-tribenzyl ether, while that using KOH or RbOH gave the 2,4,6-isomer as the main product. Methyl β-D-galactopyranoside afforded the 3,4,6-tribenzyl ether predominantly, irrespective of the alkali used.
甲基 α-D-吡喃半乳糖苷与苄基氯和 LiOH 选择性地部分苄基化得到 2,3,6-三苄基醚,而使用 KOH 或 RbOH 得到 2,4,6-异构体作为主要产物。无论使用何种碱,甲基 β-D-吡喃半乳糖苷主要提供 3,4,6-三苄基醚。
