Volvalerelactones A and B (1 and 2), two new sesquiterpenoid lactones with an unprecedented 3/7/6 tricyclic ring system, were isolated from the roots of Valeriana officinalis var. latifolia. Their structures and relative configurations were elucidated by spectroscopic data and single-crystal X-ray diffraction crystallography, and the absolute configuration was assigned by computational methods. The possible biosynthetic pathways of 1 and 2 were also proposed.
缬草内酯 A 和 B(1 和 2)是两种新型倍半萜内酯,具有前所未有的 3/7/6 三环体系,从宽叶缬草根中分离得到。通过光谱数据和单晶 X 射线衍射结晶学阐明了它们的结构和相对构型,并通过计算方法确定了绝对构型。还提出了 1 和 2 的可能生物合成途径。
