STRUCTURAL AND ABSOLUTE CONFIGURATIONAL STUDIES OF STRIATENE, STRIATOL AND (β-MONOCYCLONEROLIDOL, THREE SESQUITERPENOIDS FROM THE LIVERWORTPTYCHANTHUS STRIATUS(LEHM. ET LINDEMB.) NEES
摘要:
从肝草 Ptychanthus striatus(Lehm. et Lindemb.) Nees 中分离出了三种新的倍半萜化合物,即条纹烯、条纹醇和β-单环烯醇。这些化合物对于研究肝草从藻类进化而来的过程具有重要意义。

The first enantioselective synthesis of natural striatene (+)-1, isolated from liverwort Ptychanthus striatus, starting from commercially available (R)-Pulegone is described. Its stereostructure was confirmed by X-ray analysis of a 3,5-dinitrobenzoate derivative obtained from a key intermediate and its high optical purity was verified by chiral HPLC.
