The gas chromatographic enantiomer separation of alpha-ionone was studied with three different chiral stationary phases using as chiral selectors: (1) heptakis(2,3,6-tri-O-methyl)-beta-cyclodextrin, dissolved in polysiloxane PS-086, (2) octakis(2,6-di-O-pentyl-3-O-trifluoroacetyl)-gamma-cyclodextrin and (3) octakis(2,6-di-O-pentyl-3-O-butanoyl)-gamma-cyclodextrin, both dissolved in polysiloxane SE-54. The influence of the concentration

The Ziegler intermediate, useful for the total synthesis of forskolin, was synthesized in 10 reaction steps starting from commercially available alpha-ionone. This highly efficient synthesis relies on the success of two consecutive highly regio- and stereoselective rearrangements. The current synthesis
