Rhodium catalyzed hydroformylation of kaurane derivatives: a route to new diterpenes with potential bioactivity
Peixoto, Andreia F.; de Melo, Daniela S.; Fernandes, Tania F.; Fonseca V., Yuraima J.; Gusevskaya, Elena V.; Silva, Artur M. S.; Contreras, Ricardo Rafael; Reyes, Marisela del C.; Usubillaga, Alfredo; Dos Santos, Eduardo N.; Pereira, Mariette M.; Bayón, J. Carles (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
Novoa, María Luisa; Reyes, Marisela del C.; Contreras, Ricardo Rafael; Da Silva, Jose G.; Balanta, Angelica; Barros, Humberto J. V.; Bolaños, Alberto; Gusevskaya, Elena V.; Dos Santos, Eduardo N. (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 ...
