Ent-Clerodane derivatives from Chromolaena connivens
Phytochemistry, 1989 Abstract The aerial parts of Chromolaena connivens afforded in addition to widespread compounds four ent -clerodane derivatives and two epimeric prostaglandin-like acids. A second species, C. turnariensis , only gave widespread compounds. The structures were elucidated by high field NMR techniques.

Enantioselective synthesis of highly functionalised cyclohexanones starting from R-(-)-Carvone.
, 1998 Copper (I) catalysed conjugate addition of methylmagnesium iodide to R-(−)-carvone and trapping the enolate as its trimethylsilyl enol ether, followed by a trityl perchlorate (TrClO4) catalysed Mukaiyama-aldol reaction, is an efficient method for the ...

Chemistry of clerodane diterpenes isolated from Dodonaea species in Western Australia [PDF]
, 2015 A new clerodane diterpene was isolated from the leaf resin of Dodonaea ceratocarpa in an appreciable quantity. The inherent chemistry of this new compound was studied to evaluate its potential as a starting material for the pharmaceutical industry.

Ent-clerodane derivatives and other constituents from representatives of the subgenus ageratina
, 1989 Ageratina ixiocladon afforded several p-hydroxyacetophenone derivatives and diterpenes including six new ent-clerodanes. Two further species, which are also placed in the subgenus Ageratina, gave p-hydroxyacetophenone derivatives which seem to be ...
