A method for the syntheses of Enopyranosides

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. 2009 Bentham Science Publishers Ltd.

Sodium hydride/hexamethylphosphoric triamide: A new and efficient reagent towards the synthesis of protected 1,2- and 5,6-enopyranosides

A new method for the elimination of hydrogen halides and p-toluenesulfonic acid from sugar moieties using sodium hydride (NaH) in hexamethylphosphoric triamide (HMPA) at room temperature is reported. NaH/HMPA has several advantages compared to NaH/DMF: elimination products are produced in high yields even from sterically hindered starting materials, and not only from halides, but also tosylates.
