Simirgiotis, Mario %T Further Mulinane and Azorellane Diterpenoids Isolated from Mulinum crassifolium and Azorella compacta %D 2014 %U http://hdl.handle.net/10498/20577 %X The new mulinane diterpenoids 1 and 2 were isolated from the EtOAc extract of Mulinum crassifolium, while the rearranged mulinane 5, which was isolated for the first time from a natural source, was isolated from Azorella compacta. Compounds 1–2 were prepared by semi-synthesis thorough acetylation of the diterpene 17-acetoxymulinic acid (3). A mechanism of reaction was proposed, while the structures of the new compounds were elucidated on the basis of comprehensive spectroscopic analysis and computational methods. %K mulinanes %K azorellanes %K new diterpenoids %K Chilean native plants %K semisynthesis %~ Universidad de Cádiz
