METHYL-d-GLUCOSIDE

When dextrose is heated with methanol containing a small amount of anhydrous hydrogen chloride, a-methyl-D-glucoside is obtained in good yield and can be isolated by crystallization. Similar reactions occur with higher alcohols, but the reaction products are more difficult to isolate by crystallization. Dextrose reacts with acid anhydrides in the presence of basic catalysts, yielding esters. Complete reaction gives the pentaacylated derivative. [Pg.289]

A stereocontrolled route to the native form of thromboxane B2 was carried out starting with a-methyl-D-glucoside (Ref. 3). [Pg.296]

The first published paper devoted to the VCD of sugars compared the CH stretching spectra of a- and 0-methyl-D-glucoside in D2O (110). It was found that inversion at the anomeric center produced a nearly mirror image VCD spectrum from which it was concluded that most of the CH stretching VCD... [Pg.194]

Trimethylsilyl ethers of methyl glycosides have been used in analyzing bacterial endotoxins that contain 3,6-dideoxyhexoses, and, because of the volatility of such glycosides, careful temperature-programming is essential.373 Methyl D-glucosides and analogs have been... [Pg.53]
