efforts on the total synthesis of bolivianine (1) and isobolivianine (2), involving the synthesis of onoseriolide (3). The first generation synthesis of bolivianine was completed in 21 steps by following a chiral resolution strategy. Based on the potential biogenetic relationship between bolivianine (1), onoseriolide (3), and β‐(E)‐ocimene (8), the second generation synthesis of bolivianine was biomimetically
Studies towards the Synthesis of Lindenene: Unexpected Stereochemical Outcome of an Intramolecular Cyclopropanation Reaction and Synthesis of (±)-<i>epi</i>-Lindenene and (±)-<i>iso</i>-Lindenene
Investigation towards the synthesis of the furanosesqui-terpene Lindenene using an intramolecular cyclopropanation reaction gave unexpected ring-junction isomerisation products. These products were elaborated to (±)- EPI-lindenene and (±)- ISO-lindenene.

The first synthesis of the sesquiterpene Lindenene is described. A novel non-catalysed intramolecular cyclopropanation reaction between a diazoketone and an unactivated alkene was utilised to construct the relatively labile ketone precursor with complete stereocontrol. This ketone was transformed in three steps into Lindenene.

A total synthesis of (+/-)-chloranthalactone A was completed. It features substrate-controlled epoxidation of ketone and highly diastereoselective intramolecular cyclopropanation to construct the cis, trans-3/5/6 tricyclic skeleton.
