A variety of 2,3-unsaturated- O -glycosides have been prepared by the Ferrier rearrangement of acetyl protected glycals under microwave irradiation using silica gel as an acid catalyst. Environmental friendliness, high yields, and short reaction times are the key features of this method. Furthermore, the method was applicable not only to the Ferrier reaction of 3,4,6-tri- O -acetyl glucal and 3,4,6-tri- O -acetyl galactal but also to the Ferrier reaction of 3,4-di- O -acetyl arabinal.
