Four novel naturally occurring diastereoisomers of dinor‐eudesmenes, named chloranthones A–D (1–4, resp.), were isolated as minor components from the EtOH extract of the aerial parts of Chloranthus elatior. The unprecedented framework was established using extensive 2D‐NMR techniques. Their absolute configurations were deduced from the observed Cotton effects in their circular dichroism (CD) spectra...
Five new and seven known mono‐sesquiterpenoids (1–5 and 6–12, resp.) together with five known lindenane‐type disesquiterpenoids, 13–17, were isolated from the whole plant of Chloranthus henryi. Based on spectroscopic methods, the new structures were established to be (5S,6R,8S,10R)‐6‐hydroxyeudesma‐4(15),7(11)‐diene‐12,8‐olide (1), 6α‐hydroxyeudesma‐4(15),7(11),8(9)‐triene‐12,8‐olide (2), 8,12‐epoxy‐1...
