Clerodane-type Diterpenolds from the Taiwanese Liverwort Schistochila acuminata
, 1992 Three cis-clerodane-type acids 3-5 and one methyl ester 9 were identified from the liverwort Schistochila acuminata. The two new acids 3 and 5 were 12E and 12Z geometric isomers and the methyl ester 9 was first reported from nature ...

The clerodane ring system: investigating the viability of a direct Diels-Alder approach
, 2011 A direct synthetic approach to the spiro-γ-lactone clerodane ring system has been investigated. This work builds on that of Jung and highlights the inherent difficulties associated with the otherwise obvious Diels-Alder ...
