Seven new diterpenes, jiadifenoic acids J–P (1–7), two new sesquicarane sesquiterpenes, sesquicaranoic acids A and B (8 and 9), and four known compounds, were isolated from the stems of Illicium jiadifengpi. The trans-fused A/B ring junction in diterpenes was deduced from NMR data analysis and confirmed by single-crystal X-ray crystallography of 3. The absolute configurations of compounds 1 and 5...
Nine new diterpenes, named jiadifenoic acids A–I (1–9), together with 10 known analogues were isolated from the roots of Illicium jiadifengpi. Their structures were elucidated by extensive spectroscopic analysis and circular dichroism (CD) experiments. Jiadifenoic acid A (1) is a novel dimeric diterpene with a rare spiro[bicyclo[2.2.2]-oct-5-ene-2,1′-cyclopentan]-3-one motif. A plausible biosynthetic...
