A preparative semi-synthetic method was developed to prepare 20S-protopanaxadiol 20-O-β-Dglucopyranoside (1), a metabolite of Panax ginseng glycosides. The 20-O-•-D-glucopyranosides of 20S-hydroxydammar-24-en-3,12-dione, 3β,20S-dihydroxydammar-24-en-12-one, and 3β,12α, 20S-trihydroxydammar-24-ene were synthesized for the first time.
开发了一种准备性的半合成方法,以制备人参苷的代谢产物20S-
原人参二醇20-O-β-
D-葡萄糖苷 (1)。首次合成了20S-羟基达马烯-24-酮-3,12-二酮、3β,20S-二羟基达马烯-24-酮和3β,12α,20S-三羟基达马烯-24-烯的20-O-β-
D-葡萄糖苷。
