Resumen: From Turkish tobacco Giles and Schumacher (1) isolated the two diterpene lactones β- and α-levantenolide, for which they proposed structures 1 and 2 respectively on the basis of chemical degradative work and spectral data.
As shown below, the stereochemistry of these compounds at C12 must be revised in the light of spectroscopic studies.
