一般描述
Benzaldehyde dimethyl acetal is an organic building block. Pyridinium tosylate-catalyzed acetal exchange reaction between benzaldehyde dimethyl acetal and 6-O-(tert-butyldiphenylsilyl)-1,2-O-isopropylidene-α-D-glucofuranose is reported to afford 3,5-O-benzylidene-1,2-O-isopropylidene-α-D-glucofuranose. The kinetics of the hydrolysis of benzaldehyde dimethyl acetal over amberlite IR-120 has been studied using a circulated batch reactor in dioxane. One-pot tandem conversion of benzaldehydedimethylacetal to trans-1-nitro-2-phenylethylene has been reported.
应用
Benzaldehyde dimethyl acetal is suitable for use in the synthesis of 4,6-dihydroxy sugar, required for the total synthesis of Porphyromonas gingivalis 381 derived lipid A. It may be used in the preparation of 1-O-methyl-2,3-di-O-galloyl-β-D-glucose.

Pyridinium tosylate-catalyzed acetal exchange between benzaldehyde dimethyl acetal and 6-O-(tert-butyldiphenylsilyl)-1,2-O-isopropylidene-alpha-D-glucofu ranose was investigated as an alternative to the original procedure of Brigl and Grüner (condensation of a D-glucose triol with benzaldehyde under zinc halide catalysis) for synthesis of 3,5-O-benzylidene-1,2-O-isopropylidene-alpha-D-glucofuranose.

The clove ellagitannins and their related polygalloyl-glucoses inhibited maltase activity of rat intestinal alpha-glucosidases. The structure-activity relationship study of those galloylglucoses, varying the extent of galloylation on the glucose core, with the ellagitannins, indicated that an increasing number of galloyl
