- 中文摘要: 經由各種有關衍生物的NMR及MS譜圖加以比較的結果,可證明marsformol的構造中C-13上的H原子為axial con-figuration。 另一方面,由α-amyrin acetate可合成Marsformol,同時得到C-11 α-hydroxy epimer,此化合物亦經若干反應以確定其結構。
- 英文摘要: In this report, the configuration of the C-13 proton in marsformol was established in the axial orien-tation, based on its NMR and MS spectra and structural relations with other related derivatives. Also thepartial synthesis of marsformol was achieved in a few steps from α-amyrin acetate, and the C-11 α-hydroxylepimer of marsformol characterized by the chemical and the physical evidences was also obtained.
