Rhodium catalyzed hydroformylation of kaurane derivatives: a route to new diterpenes with potential bioactivity
(2010-11-25)
Kaurenic and grandiflorenic acids are naturally occurring diterpenes whose biological activity has beedescribed. Both acids contain an exocyclic methylenic double bond that allows further functionalization on their structure. ...
Rhodium catalyzed hydroformylation of monoterpenes containing a sterically encumbered trisubstituted endocyclic double bond under mild conditions
(2010-11-25)
The rhodium catalyzed hydroformylation of endocyclic monoterpenes, that is, 2-carene (1), 3-carene (2), and a-pinene (3), in the presence of PPh3 or various diphosphines and phosphites has been studied. The unmodified Rh ...
