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.

Sesquiterpenoid Constituents of the Liverwort,<i>Ptychanthus striatus</i>(LEHM. et LINDENB.) NEES
Four sesquiterpenoids, striatene, striatol, β-monocyclonerolidol and ptychanolide, were isolated from the liverwort Ptychanthus striatus (LEhm. et. LIndenb.)NEes. Their structures have been established by spectroscopic analysis and chemical transformation. Three of them, striatene, striatol and β-monocyclonerolidol, are interesting in terms of the evolution of the liverwort from the algae.
