Astrophylline Description
Source: The woods of Acacia catechu (L.F.) Willd.
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.

Total synthesis of (+)-astrophylline.[Pubmed: 12662069]

METHODS AND RESULTS:
The first total synthesis of (+)-Astrophylline (2) has been achieved, starting from readily available enantiomerically pure (+)-(1R,4S)-4-hydroxycyclopent-2-enyl acetate (11). A novel ruthenium-catalyzed ring-closing ring-opening ring-closing metathesis of carbocyclic olefins of general type 5 was the key step, providing the stereochemically well-defined bis-piperidyl skeleton of the target molecule. A [2,3]-Wittig-Still rearrangement of 9 was also employed as the critical transformation in the stereocontrolled generation of the 1,2-trans configuration of the cyclopentene intermediate 6c.
CONCLUSIONS:
Our early synthetic efforts toward 1,2-trans cyclopentene derivatives of type 6, as well as the synthetic pathway to an optimized 13-step total synthesis of (+)-Astrophylline (12% overall yield), are reported.
