Abstract: 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.
Description: 2 pages, 1 table, 1 scheme.
