Biological Activity
Description: 1,2:4,5-di-O-isopropylidene-beta-D-fructopyranose is a synthetic precursor of the asymmetric epoxidation catalyst 1,2:4,5-di-O-isopropylidene-beta-D-erythro-2,3- hexadiulo-2,6-pyranose.
1,2:4,5-Di-O-isopropylidene-beta-D-fructopyranose Description
Source: The herbs of Euphorbia macroclada.
Solvent: Chloroform, Dichloromethane, Ethyl Acetate, DMSO, Acetone, etc.
Storage: Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months(2-8C).

Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20C. Generally, these will be useable for up to two weeks. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.

Need more advice on solubility, usage and handling? Please email to: service@chemfaces.com

After receiving: The packaging of the product may have turned upside down during transportation, resulting in the natural compounds adhering to the neck or cap of the vial. take the vial out of its packaging and gently shake to let the compounds fall to the bottom of the vial. for liquid products, centrifuge at 200-500 RPM to gather the liquid at the bottom of the vial. try to avoid loss or contamination during handling.

Selective ruthenium-catalyzed oxidation of 1,2:4,5-di-O-isopropylidene- beta-D-fructopyranose and other alcohols with NaOCl.[Pubmed: 12000267]

METHODS AND RESULTS:
The asymmetric epoxidation catalyst 1,2:4,5-di-O-isopropylidene-beta-D-erythro-2,3-hexadiulo-2,6-pyranose 2 was obtained in high yield from 1,2:4,5-Di-O-isopropylidene-beta-D-fructopyranose 1 via a recyclable ruthenium-catalyzed hypochlorite oxidation protocol under biphasic conditions (MTBE/water) in the presence of an alkaline buffer (pH 9.5). Other secondary alcohols were also oxidized selectively to the corresponding ketones.
