Herein we describe the totalsynthesis of five guaianolide natural products: thapsigargin, thapsivillosin C, thapsivillosinF, trilobolide and nortrilobolide. Prodrug derivatives of thapsigargin have shown selective in vivo cytotoxicity against prostate tumours and the need for further investigation of this phenomenon highlights the importance of these total syntheses. The first absolute stereochemical
A highly efficient route was developed to synthesize (−)-8-epigrosheimin in four steps from aldehyde 2 based on a substrate-controlled method. The key steps of the synthesis included (1) a stereo- and regioselective allylation addition, (2) an intramolecular translactonization, and (3) an aldehyde-ene cyclization.

A study towards diversity-oriented synthesis of optically active cyclopentane fused bicyclic frameworks has been accomplished. The common intermediate was prepared from commercially available starting material (S)-carvone. The observations on competition between Grubbs-II catalyzed ringclosingmetathesis (RCM) and ringclosing carbonyl-olefin metathesis (RCCOM) were the key features of the study.

Diastereomeric 2′-amino-3′-cyano-6′-methyl-2-oxospiro[indolin-3,4′-pyran]-5′-carboxylates based on transformation products of (+)-3-carene and (–)-carvone were synthesized for the first time.
