We applied nucleophilic substitution to 6-O-tosyl-1,2:3,4-di-O-isopropylidene-α-D-galactopyranose using sulphur nucleophiles and obtained 6-S-derivatives of 1,2:3,4-di-O-isopropylidene-α-D-galactopyranose. We present the physical and spectroscopic characterization of these heterocyclic compounds as well as other related compounds obtained by substitution, using other substrates. The conformational
我们使用硫亲核试剂对6 - O-甲苯磺酰基-1,2:3,4-二-O-异亚丙基-α- D-吡喃半乳糖应用亲核取代反应,获得了1,2:3,4-di的6- S-衍生物- Ø异亚丙基α- d -galactopyranose。我们介绍了这些杂环化合物以及使用其他底物通过取代获得的其他相关化合物的物理和光谱表征。介绍并讨论了所有产品的构象研究。
