Fernene Triterpenoids from the Lichen Pyxine berteriana
(American Chemical Society, 2009-09-16)
Two new fernene triterpenoids, fern-9(11)-en-3,19-dione (1) and 3beta-acetoxyfern-9(11)-en-19-one (2), together with the known 3beta-acetoxyfern-9(11)-en-19beta-ol (3) and lichexanthone (4), have been isolated from the ...
Correlation Between Experimental and DFT/GIAO Computed 13C NMR Chemical Shifts. A Theoretical Study on Pentacyclic Terpenoids (fernenes)
(Elsevier Science, 2010-08)
The 13C chemical shifts of 15 pentacyclic terpenoids (fernenes) are compared to predicted 13C NMR chemical shifts obtained via empirically scaled GIAO shieldings. We report that accurate (rms error approx. 1.5 ppm) predictions ...
