Abstract
Sodium hydride (NaH) in hexamethylphosphoric triamide (HMPA) has been introduced as an economical and efficient reagent towards the creation of 1,2- or 5,6-enopyranosides from the corresponding halogenated or tosylated pyranosides. NaH/HMPA has several advantages compared to NaH/DMF: elimination products are produced in high yields even from sterically-hindered halides as well as tosylates.
Keywords: Enopyranosides, sodium hydride/hexamethylphosphoric triamide, carbohydrates
