USES:
- Methyl-4, 6-benzylidene -α -D-glucopyranoside is a commonly used benzylidene protected carbohydrate derivative, usually as an intermediate, widely used in the synthesis of a variety of compounds.
The specific application is described as follows:
- By synthesizing a deacetyllanatoside glucosyl-modified compound (2-O-benzyl-beta-D-glucopyranoside-deacetyllanatoside and the like) to enhance the antitumous effect of the compound, the potency is improved, the half-life period is prolonged, meanwhile, the modified compound is prepared into a liposome, the hepatic targeting effect of the liposome is improved, and the cardiotoxicity is reduced.
- It is used for the construction of chiral trifluoromethylated quaternary carbon centres
- Synthesis of new C-6 homologues of 1-deoxynojirimycin and 1-deoxy- L –idonojirimycin.
- Use of Propargyl Glycoside for Anomeric Protection
- Synthesis of phenylurethane.
- It is used for synthesis and antimicrobial studies of pyranmycin.
- Synthesis of several Alkyl Hex-3-enopyranosiduloses.
- This product reacts with dibromomethane in aqueous solution of sodium hydroxide, using tetrabutylammonium bromide as phase transfer agent, can obtain corresponding 2, 3-methylene acetal. This product protects the 4th and 6th positions
- This product can be oxidated and ring opened by n-bromosuccinimide (NBS), and generate 6-bromo-4-O-benzoyl pyranhexose.
