Argutalactone, an unprecedented sesquiterpenoid lactone with a 6/5/7 tricyclic system from Incarvillea arguta

A concise asymmetric total synthesis for structure elucidation of 5,6-secoiridoid from Incarvillea argute

A phytochemical investigation of the roots of Incarvillea arguta led to the isolation of secoarguterin (1), which is the first example of 5,6-secoiridoid.

Natural sesquiterpenoids

This review covers the isolation, structural determination, synthesis and chemical and microbiological transformations of natural sesquiterpenoids. The literature from January to December 2012 is reviewed, and 471 references are cited.
