Synthesis of both monobenzenesulfonates of isosorbide (1,4:3,6-dianhydrosorbitol) was regioselectively achieved in high yields via a three-step sequence. These monoesters were O-alkylated before being reacted with various primary amines to give the corresponding amino ethers. The full control of regioselectivity led either to the exo-exo or endo-endo isomers. In an independent pathway, isosorbide derived
异山梨醇(1,4:3,6-二脱水山梨糖醇)的两种单苯磺酸盐的合成通过三步顺序以高产率区域选择性地实现。在与各种伯胺反应以得到相应的氨基醚之前,将这些单酯进行O-烷基化。区域选择性的完全控制导致了exo-exo或endo-endo异构体。在一个独立的途径中,异山梨醇衍生的氨基醚和氨基醇在内位具有氨基和羟基功能,是通过四步法从异山梨醇合成的,该过程包括选择性的单苄基化,甲苯磺酸化,胺取代和脱苄基作用。
