| titleOfInvention | A kind of synthetic method of Astragalus membranacus saponin(e II |
| abstract | The invention discloses a kind of synthetic methods of Astragalus membranacus saponin(e II, include the following steps：(1) pass through 3 hydroxyls of TBS selective protection cycloastragenol；(2) 6,16,20 hydroxyls of cycloastragenol, 3 hydroxyls of (3) selectively removing are protected by Ac；(4) 3 glycosidic bonds are constructed；(5) it removes protecting group all in molecule and obtains Astragalus membranacus saponin(e II.The method of the present invention effectively realizes the differentiation of 3 hydroxyls in cycloastragenol, 3 constructed the glycosidic bond of high-efficiency high-stereoselectivity, effective synthesis Astragalus membranacus saponin(e II, the blank for having filled up the prior art will promote the activity mechanism research and its process of drug development of Astrageloside compound significantly. |
