Abstract
null null Two epimers, 20S,24R-epoxy dammarane-3β,12β,25-triol (3) and 20S,24S-epoxy dammarane-3β,12β,25-triol (4) were prepared from 20(S)-protopanaxadiol, which were confirmed by ESI-MS, NMR, and X-ray single-crystal diffraction. The results indicate the configuration of C-24 of 3 and 4 are R-form and S-form, respectively. 3 and 4 crystallize in a orthorhombic space group P2(1)2(1)2(1). Compound 3 have more complicated intramolecular hydrogen...
